<br />
I am currently working on a novel temporal pixel multiplexing camera. At the heart of it is a novel CMOS chip - the TPM. It offers a novel way of capturing images in low light a a very high frame rate, with user-customizable frame interleaving. The chip has been manufactured and is under rigorous characterization now. I'm working with [[Roger Light|Roger]] on this project.<br />
<br />
I also work on the use of a novel laser ultrasound detector, the Speckle Knife Edge Detector (SKED). I recently spent a year characterizing it and investigating its feasibility for field work. The SKED is currently under test as a suitable detector in a [[SRAS for materials characterisation|SRAS]] system, especially for components with rough surfaces. I'm working with [[Rikesh Patel|Rikesh]], [[Roger Light|Roger]] and [[Steve Sharples|Steve]] on this project.<br />

This means that complicated and expensive setups are required to detect ultrasound optically on rough surfaces. We present a CMOS integrated circuit that can detect laser ultrasound in the presence of speckle. The detector circuit is based on the simple knife edge detector. It is self-adapting and is fast, inxepensive, compact and robust. The CMOS circuit is implemented as a widefield array of 32×32 pixels. At each pixel the received light is compared with an adjacent pixel in order to determine the local light gradient. The result of this comparison is stored and used to connect each pixel to the positive or negative gradient output as appropriate (similar to a balanced knife edge detector). The perturbation of the surface due to ultrasound preserves the speckle distribution whilst deflecting it. The spatial disturbance of the speckle pattern due to the ultrasound is detected by considering each pair of pixels as a knife edge detector. The sensor can adapt itself to match the received optical speckle pattern in less than 0.1 μs, and then detect the ultrasound within 0.5 μs of adaptation. This makes it possible to repeatedly detect ultrasound from optically rough surfaces very quickly. The detector is capable of independent operation controlled by a local microcontroller, or it may be connected to a computer for more sophisticated configuration and control. We present the theory of its operation and discuss results validating the concept and operation of the device. We also present preliminary results from an improved design which grants a higher bandwidth, allowing for optical detection of higher frequency ultrasound.} }<br />

It is particularly suitable for detection of high frequency surface acoustic waves as the response is proportional to variation of the local tilt of the surface. In the case of a specular reflection of the incident laser beam from a smooth surface, any lateral movement of the reflected beam caused by the ultrasonic waves is easily detected by a pair of photodiodes. The major disadvantage of the knife edge detector is that it does not cope well with optically rough surfaces, those that give a speckled reflection. The optical speckles from a rough surface adversely affect the efficiency of the knife edge detector, because 'dark' speckles move synchronously with 'bright' speckles, and their contributions to the ultrasonic signal cancel each other out. We have developed a new self-adapting sensor which can cope with the optical speckles reflected from a rough surface.

'''Current Research'''<br />
<br />
I am currently working on a novel temporal pixel multiplexing camera. At the heart of it is a novel CMOS chip - the TPM. It offers a novel way of capturing images in low light a a very high frame rate, with user-customizable frame interleaving. The chip has been manufactured and is under rigorous characterization now. I'm working with [[Roger Light|Roger]] on this project.<br />
<br />
I also work on the use of a novel laser ultrasound detector, the Speckle Knife Edge Detector (SKED). I recently spent a year characterizing it and investigating its feasibility for field work. The SKED is currently under test as a suitable detector in a [[SRAS for materials characterisation|SRAS]] system, especially for components with rough surfaces. I'm working with [[Rikesh Patel|Rikesh]], [[Roger Light|Roger]] and [[Steve Sharples|Steve]] on this project.<br />

This means that complicated and expensive setups are required to detect ultrasound optically on rough surfaces. We present a CMOS integrated circuit that can detect laser ultrasound in the presence of speckle. The detector circuit is based on the simple knife edge detector. It is self-adapting and is fast, inxepensive, compact and robust. The CMOS circuit is implemented as a widefield array of 32×32 pixels. At each pixel the received light is compared with an adjacent pixel in order to determine the local light gradient. The result of this comparison is stored and used to connect each pixel to the positive or negative gradient output as appropriate (similar to a balanced knife edge detector). The perturbation of the surface due to ultrasound preserves the speckle distribution whilst deflecting it. The spatial disturbance of the speckle pattern due to the ultrasound is detected by considering each pair of pixels as a knife edge detector. The sensor can adapt itself to match the received optical speckle pattern in less than 0.1 μs, and then detect the ultrasound within 0.5 μs of adaptation. This makes it possible to repeatedly detect ultrasound from optically rough surfaces very quickly. The detector is capable of independent operation controlled by a local microcontroller, or it may be connected to a computer for more sophisticated configuration and control. We present the theory of its operation and discuss results validating the concept and operation of the device. We also present preliminary results from an improved design which grants a higher bandwidth, allowing for optical detection of higher frequency ultrasound.} }<br />

It is particularly suitable for detection of high frequency surface acoustic waves as the response is proportional to variation of the local tilt of the surface. In the case of a specular reflection of the incident laser beam from a smooth surface, any lateral movement of the reflected beam caused by the ultrasonic waves is easily detected by a pair of photodiodes. The major disadvantage of the knife edge detector is that it does not cope well with optically rough surfaces, those that give a speckled reflection. The optical speckles from a rough surface adversely affect the efficiency of the knife edge detector, because 'dark' speckles move synchronously with 'bright' speckles, and their contributions to the ultrasonic signal cancel each other out. We have developed a new self-adapting sensor which can cope with the optical speckles reflected from a rough surface. It is inelegantly called the SKED—speckle knife edge detector—and like its smooth surface namesake it is simple, cheap, compact, and robust. We describe the theory of its operation, and present preliminary experimental results validating the overall concept and the operation of the prototype device.} }<br />

The interferograms are captured using a custom CMOS modulated light camera (MLC) which is capable of demodulating light in the megahertz region. Two stabilised HeNe lasers were constructed in order to keep the optical frequency difference (beat frequency) between the beams within the operational range of the camera.This system is based on previously reported work of an ultrastable heterodyne interferometer \&\#x0005B;Opt. Express 20, 17722 (2012)\&\#x0005D;. The system used an electronic feedback system to mix down the heterodyne signal captured at each pixel on the camera to cancel out the effects of time varying piston phase changes observed across the array. In this paper, a similar technique is used to track and negate the effects of beat frequency variations across the two laser pattern. This technique makes it possible to capture the full field interferogram caused by interfering two independent lasers even though the beat frequency is effectively random.As a demonstration of the system\&\#x02019;s widefield interferogram capture capability, an image of a phase shifting object is taken using a very simple two laser interferometer.}, Doi = {10.1364/OE.22.027094}, Keywords = {Interferometric imaging ; Interferometric imaging}, Owner = {rp}, Publisher = {OSA}, Timestamp = {2014.11.18}, Url = {http://www.opticsexpress.org/abstract.cfm?URI=oe-22-22-27094}, pdf = { http://optics.eee.nottingham.ac.uk/w/images/4/4d/Pap4.pdf} }<br />

This uses a modulated light camera (MLC) to capture and stabilise the interferogram in the widefield heterodyne interferometer. This system eliminates the contribution of piston phase to the interferogram without the need for common path optics and results in a highly stable widefield interferometer.The MLC uses quadrature demodulation circuitry built into each pixel to demodulate the light signal and extract phase information using an electronic reference signal. In contrast to the work previously presented \&\#x0005B;Opt. Express 19, 24546 (2011)\&\#x0005D;, the reference signal is derived from one of the pixels on board the MLC rather than an external source. This local reference signal tracks the instantaneous modulation frequency detected by the other pixels and eliminates the contribution of piston phase to the interferogram, substantially removing the contributions of unwanted vibrations and microphonics to the interferogram. Interferograms taken using the ultrastable system are presented with one of the interferometer mirrors moving at up to 85 mm s\&\#x02212;1 over a variety of frequencies from 18 Hz to 20 kHz (giving a variation in optical path length of 220 \&\#x003BC;m, or 350 wavelengths at 62 Hz). This limit was the result of complex motion in the mirror mount rather than the stability limit of the system.

'''Current Research'''<br />
<br />
I am currently working on a novel temporal pixel multiplexing camera. At the heart of it is a novel CMOS chip - the TPM. It offers a novel way of capturing images in low light a a very high frame rate, with user-customizable frame interleaving. The chip has been manufactured and is under rigorous characterization now. I'm working with [[Roger Light|Roger]] on this project.<br />
<br />
I also work on the use of a novel laser ultrasound detector, the Speckle Knife Edge Detector (SKED). I recently spent a year characterizing it and investigating its feasibility for field work. The SKED is currently under test as a suitable detector in a [[SRAS for materials characterisation|SRAS]] system, especially for components with rough surfaces. I'm working with [[Rikesh Patel|Rikesh]], [[Roger Light|Roger]] and [[Steve Sharples|Steve]] on this project.<br />

This means that complicated and expensive setups are required to detect ultrasound optically on rough surfaces. We present a CMOS integrated circuit that can detect laser ultrasound in the presence of speckle. The detector circuit is based on the simple knife edge detector. It is self-adapting and is fast, inxepensive, compact and robust. The CMOS circuit is implemented as a widefield array of 32×32 pixels. At each pixel the received light is compared with an adjacent pixel in order to determine the local light gradient. The result of this comparison is stored and used to connect each pixel to the positive or negative gradient output as appropriate (similar to a balanced knife edge detector). The perturbation of the surface due to ultrasound preserves the speckle distribution whilst deflecting it. The spatial disturbance of the speckle pattern due to the ultrasound is detected by considering each pair of pixels as a knife edge detector. The sensor can adapt itself to match the received optical speckle pattern in less than 0.1 μs, and then detect the ultrasound within 0.5 μs of adaptation. This makes it possible to repeatedly detect ultrasound from optically rough surfaces very quickly. The detector is capable of independent operation controlled by a local microcontroller, or it may be connected to a computer for more sophisticated configuration and control. We present the theory of its operation and discuss results validating the concept and operation of the device. We also present preliminary results from an improved design which grants a higher bandwidth, allowing for optical detection of higher frequency ultrasound.} }<br />

It is particularly suitable for detection of high frequency surface acoustic waves as the response is proportional to variation of the local tilt of the surface. In the case of a specular reflection of the incident laser beam from a smooth surface, any lateral movement of the reflected beam caused by the ultrasonic waves is easily detected by a pair of photodiodes. The major disadvantage of the knife edge detector is that it does not cope well with optically rough surfaces, those that give a speckled reflection. The optical speckles from a rough surface adversely affect the efficiency of the knife edge detector, because 'dark' speckles move synchronously with 'bright' speckles, and their contributions to the ultrasonic signal cancel each other out. We have developed a new self-adapting sensor which can cope with the optical speckles reflected from a rough surface. It is inelegantly called the SKED—speckle knife edge detector—and like its smooth surface namesake it is simple, cheap, compact, and robust. We describe the theory of its operation, and present preliminary experimental results validating the overall concept and the operation of the prototype device.} }<br />

Express}, Year = {2014}, Month = {Nov}, Number = {22}, Pages = {27094--27101}, Volume = {22}, Abstract = {A novel system has been developed that can capture the wide-field interference pattern generated by interfering two independent and incoherent laser sources. The interferograms are captured using a custom CMOS modulated light camera (MLC) which is capable of demodulating light in the megahertz region. Two stabilised HeNe lasers were constructed in order to keep the optical frequency difference (beat frequency) between the beams within the operational range of the camera.This system is based on previously reported work of an ultrastable heterodyne interferometer \&\#x0005B;Opt. Express 20, 17722 (2012)\&\#x0005D;. The system used an electronic feedback system to mix down the heterodyne signal captured at each pixel on the camera to cancel out the effects of time varying piston phase changes observed across the array. In this paper, a similar technique is used to track and negate the effects of beat frequency variations across the two laser pattern. This technique makes it possible to capture the full field interferogram caused by interfering two independent lasers even though the beat frequency is effectively random.As a demonstration of the system\&\#x02019;s widefield interferogram capture capability, an image of a phase shifting object is taken using a very simple two laser interferometer.}, Doi = {10.1364/OE.22.027094}, Keywords = {Interferometric imaging ; Interferometric imaging}, Owner = {rp}, Publisher = {OSA}, Timestamp = {2014.11.18}, Url = {http://www.opticsexpress.org/abstract.cfm?URI=oe-22-22-27094}, pdf = { http://optics.eee.nottingham.ac.uk/w/images/4/4d/Pap4.pdf} }<br />

Express}, year = {2012}, volume = {20}, pages = {17722--17733}, number = {16}, month = {Jul}, abstract = {A novel ultrastable widefield interferometer is presented. This uses a modulated light camera (MLC) to capture and stabilise the interferogram in the widefield heterodyne interferometer. This system eliminates the contribution of piston phase to the interferogram without the need for common path optics and results in a highly stable widefield interferometer.The MLC uses quadrature demodulation circuitry built into each pixel to demodulate the light signal and extract phase information using an electronic reference signal. In contrast to the work previously presented \&\#x0005B;Opt. Express 19, 24546 (2011)\&\#x0005D;, the reference signal is derived from one of the pixels on board the MLC rather than an external source. This local reference signal tracks the instantaneous modulation frequency detected by the other pixels and eliminates the contribution of piston phase to the interferogram, substantially removing the contributions of unwanted vibrations and microphonics to the interferogram. Interferograms taken using the ultrastable system are presented with one of the interferometer mirrors moving at up to 85 mm s\&\#x02212;1 over a variety of frequencies from 18 Hz to 20 kHz (giving a variation in optical path length of 220 \&\#x003BC;m, or 350 wavelengths at 62 Hz). This limit was the result of complex motion in the mirror mount rather than the stability limit of the system. The system is shown to be insensitive to pure piston phase variations equivalent to an object velocity of over 3 m s\&\#x02212;1.}, doi = {10.1364/OE.20.017722}, keywords = {Interferometric imaging ; Interferometric imaging}, owner = {rp}, publisher = {OSA}, timestamp = {2013.06.03}, url = {http://www.opticsexpress.org/abstract.cfm?URI=oe-20-16-17722}, pdf = {http://optics.eee.nottingham.ac.uk/w/images/0/0f/Pap3.pdf}}<br />

<hr />
<div>Back to [[Linux How-tos]]<br />
<br />
== Introduction ==<br />
<br />
The Applied Optics group has been allocated some file storage space by IS. It is backed up. Access via Linux has to be requested, so talk to Steve or Roger if you'd like access. It appears that once you get access, it is also linked to your Z drive available [http://files.nottingham.ac.uk files.nottingham.ac.uk].<br />
<br />
<br />
Please note that once you mount the drive, you have total read+write access. Use with care.<br />
<br />
<br />
== Mounting the drive ==<br />
<br />
To do this, you need to be root. If you don't know how to do this, are scared of doing this, or don't know the password, then ask someone who does. You should know who that is. <br />
<br />
<br />
So, first make a directory which will host the mounted file system. At a command prompt, enter:<br />
<br />
sudo mkdir /mnt/aog_disk<br />
<br />
You'll be asked for the root password (of the linux computer you're working on).<br />
<br />
<br />
The command to "mount" (ie access) the filestore is:<br />
<br />
sudo mount -t cifs //uon4.ad.nottingham.ac.uk/r01/AOG-Linux /mnt/aog_disk -o username=uon_user_name,uid=aog_user_name<br />
<br />
You'll be asked for your UoN password.<br />
<br />
uon_user_name is your UoN username, used for email etc.<br />
<br />
aog_user_name is your AoG username, used with the AoG linux network<br />
<br />
<br />
If you enter both passwords correctly then you'll get no error, and when you cd aog_disk you'll be able to see the files. You should be able to read and write to all files, so caution is adviced. <br />
<br />
<br />
== Unmounting the drive ==<br />
<br />
<br />
To unmount:<br />
<br />
sudo umount /mnt/aog_disk<br />
<br />
enter root password. ls /mnt/aog_disk should return an empty directory now.<br />
<br />
<br />
Cheers,<br />

<br />
== Introduction ==<br />
<br />
The Applied Optics group has been allocated some file storage space by IS. It is backed up. Access via Linux has to be requested, so talk to Steve or Roger if you'd like access. It appears that once you get access, it is also linked to your Z drive available [http://files.nottingham.ac.uk files.nottingham.ac.uk].<br />
<br />
Please note that once you mount the drive, you have total read+write access. Use with care.<br />
<br />
<br />
== Mounting the drive ==<br />
<br />
To do this, you need to be root. If you don't know how to do this, are scared of doing this, or don't know the password, then ask someone who does. You should know who that is. <br />
<br />
<br />
So, first make a directory which will host the mounted file system. At a command prompt, enter:<br />
<br />
sudo mkdir /mnt/aog_disk<br />
<br />
You'll be asked for the root password (of the linux computer you're working on).<br />
<br />
<br />
The command to "mount" (ie access) the filestore is:<br />
<br />
sudo mount -t cifs //uon4.ad.nottingham.ac.uk/r01/AOG-Linux /mnt/aog_disk -o username=uon_user_name,uid=aog_user_name<br />
<br />
You'll be asked for your UoN password.<br />
<br />
uon_user_name is your UoN username, used for email etc.<br />
<br />
aog_user_name is your AoG username, used with the AoG linux network<br />
<br />
<br />
If you enter both passwords correctly then you'll get no error, and when you cd aog_disk you'll be able to see the files. You should be able to read and write to all files, so caution is adviced. <br />
<br />
<br />
== Unmounting the drive ==<br />
<br />
<br />
To unmount:<br />
<br />
sudo umount /mnt/aog_disk : enter root password<br />
<br />
aog_disk should be empty now.<br />
<br />
<br />
Cheers,<br />

Platform: Cadence/Incisive/RTL Compiler/AMS C35<br />
# VHDL to RTL<br />
## Write and test your VHDL code. You can do this with Xilinx or in any text editor. If you use a text editor you can simulate your code using NCLab.<br />
# Simulating with NCLab.<br />
## Use your favourite text editor to edit run.sh, eg: '''vi run.sh'''<br />
## At the prompt type '''./run.sh'''. This runs a little bash script that makes sure your paths, options and other parameters are correctly sent to Incisive. <br />
# VHDL to RTL<br />
## Create a folder for the RTL compiler<br />
## Copy the relevant vhdl/verilog files into the folder<br />
## Run '''rc''' at command prompt in the folder. This will generate a subfolder that RC uses to keep track of your design<br />
## At the rc prompt point to the correct process library setting attributes with: '''set_attribute library /eee/vlsi/DesignKits/AMS/v4.00/liberty/c35_3.3V/c35_CORELIB.lib'''<br />
## Read in your hdl using '''read_hdl -vhdl filename.vhd'''<br />
## To actually make sense of the design structure, elaborate your design. This converts the VHDL to an in-memory netlist. Type '''elaborate'''<br />
## Verify the design with '''check_design -all'''<br />
## View the resulting RTL schematic by typing '''gui_show''', then '''gui_raise''' to move GUI window above. Use '''gui_sync''' to keep prompt and GUI window synchronised.<br />
## You can now synthesize your vhdl to a netlist that uses cells from your chosen library. Run '''synthesize'''. Run it 3 times to optimise<br />
## Write your netlist to hdl as '''write_hdl > output.v'''<br />
## Exit rc by typing '''exit'''.<br />
# RTL to layout<br />
## Run '''ams_encounter -tech c35b4''' (generates required library files)<br />
## Run '''encounter''' at the command prompt. This starts encounter for layout planning, power planning<br />
## Choose '''File ''' >> '''Import Design''' >> '''Load''' >> '''c35b4_std.conf'''<br />
## Choose the veriloga file you've just exported<br />
## Specify '''top''' or choose '''auto'''<br />
## Save the design<br />
## Now you can go through these steps to layout<br />
### Floorplanning<br />
#### '''Floorplan''' >> '''Specify Floorplan'''<br />
#### Specify a width to length ratio. Aim for a utilization of 1. A good starting value is 0.8<br />
### Power<br />
#### Add a ring around your core<br />
#### '''Power''' >> '''Power Planning''' >> '''Add ring'''<br />
#### The power rings we want are gnd! and vdd!. <br />
#### Click ... to choose nets (pulled from netlist)<br />
#### Specify layers and width/spacing<br />
#### Add stripes to connect the rings and distribute the power more evenly<br />
#### Save design<br />
### Place end capacitors<br />
#### First place end-caps. These are fill cells that act as power decoupling/bypass capacitors.<br />
#### Do '''Place''' >> '''Physical Cell''' >> '''End Cap (R/L)'''<br />
#### Save design<br />
### Edit pins<br />
#### Click '''Edit''' >> '''Pin editor''' on the menubar<br />
#### This allows you to determine the layout of the pins. You can specify which side of the silicon block to put pins, spacing, metal layer etc.<br />
#### Click apply after each edit to save and update positions<br />
#### Save the design<br />
### Place design<br />
#### '''Place''' >> '''Place''' >> '''Standard Cell'''<br />
#### This places your design in the floorplan<br />
#### Switch to '''Physical View''' (on top right of tooolbar) to view the design<br />
#### Save the design<br />
### Save SDF/SDC data<br />
#### Do '''Timing''' >> '''Extract RC'''<br />
#### Specify a filename and save to file.<br />
### Route Power<br />
#### Choose '''Route''' >> '''Special Route'''<br />
#### This connects the power supply to your cells<br />
### Route design<br />
#### Click '''Route''' >> '''Nano Route''' >> '''Route'''<br />
#### It is a good idea to specify which metal layers should be used. We usually use Metals 1 to 3 with the C35 process. Specify this in the Routing Control, bottom:top layers section<br />
#### Save design<br />
### Export the design <br />
#### The layout is complete now, and you can export it to GDS2.<br />
#### Click '''File''' >> '''Save''' >> '''GDS/Oasis'''<br />
#### Make sure to load gds.map<br />
#### Save as filename.gds<br />
## Layout into Cadence<br />

<hr />
<div>This is a quick flow for digital IC design flow.<br />
<br />
Please borrow the MSC/STFC Introduction to Digital IC Design Flows from Roger Light (x13233).<br />
<br />
Platform: Cadence/Incisive/RTL Compiler/AMS C35<br />
# VHDL to RTL<br />
## Write and test your VHDL code. You can do this with Xilinx or in any text editor. If you use a text editor you can simulate your code using NCLab.<br />
## Create a folder for the RTL compiler<br />
## Copy the relevant vhdl/verilog files into the folder<br />
## Run '''rc''' at command prompt in the folder. This will generate a subfolder that RC uses to keep track of your design<br />
## At the rc prompt point to the correct process library setting attributes with: '''set_attribute library /eee/vlsi/DesignKits/AMS/v4.00/liberty/c35_3.3V/c35_CORELIB.lib'''<br />
## Read in your hdl using '''read_hdl -vhdl filename.vhd'''<br />
## To actually make sense of the design structure, elaborate your design. This converts the VHDL to an in-memory netlist. Type '''elaborate'''<br />
## Verify the design with '''check_design -all'''<br />
## View the resulting RTL schematic by typing '''gui_show''', then '''gui_raise''' to move GUI window above. Use '''gui_sync''' to keep prompt and GUI window synchronised.<br />
## You can now synthesize your vhdl to a netlist that uses cells from your chosen library. Run '''synthesize'''. Run it 3 times to optimise<br />
## Write your netlist to hdl as write_hdl > output.v<br />
## Exit rc by typing rc.<br />
# RTL to layout<br />
## Run '''ams_encounter -tech c35b4''' (generates required library files)<br />
## Run '''encounter''' at the command prompt. This starts encounter for layout planning, power planning<br />
# Choose '''File ''' >> '''Import Design''' >> '''Load''' >> '''c35b4_std.conf'''<br />
## Choose the veriloga file you've just exported<br />
## Specify '''top''' or choose '''auto'''<br />
## Save the design<br />
## Now you can go through these steps to layout<br />
### Floorplanning<br />
#### '''Floorplan''' >> '''Specify Floorplan'''<br />
#### Specify a width to length ratio. Aim for a utilization of 1. A good starting value is 0.8<br />
### Power<br />
#### '''Power''' >> '''Power Planning''' >> '''Add ring'''<br />
#### The power rings we want are gnd! and vdd!. <br />
#### Click ... to choose nets (pulled from netlist)<br />
#### Specify layers and width/spacing<br />
#### Add stripes to connect the rings and distribute the power more evenly<br />
#### Save design<br />
### Place end capacitors<br />
#### First place end-caps. These are fill cells that act as power decoupling/bypass capacitors.<br />
#### Do '''Place''' >> '''Physical Cell''' >> '''End Cap (R/L)'''<br />
#### Save design<br />
### Edit pins<br />
#### Edit >> Pin editor<br />
#### This allows you to determine the layout of the pins. You can specify which side of the silicon block to put pins, spacing, metal layer etc.<br />
#### Click apply after each edit to save and update positions<br />
#### Save the design<br />
### Place design<br />
#### '''Place''' >> '''Place''' >> '''Standard Cell'''<br />
#### This places your design in the floorplan<br />
#### Switch to '''Physical View''' (on top right of tooolbar) to view the design<br />
#### Save the design<br />
### Save SDF/SDC data<br />
#### Do '''Timing''' >> '''Extract RC'''<br />
#### Specify a filename and save to file.<br />
### Route Power<br />
#### Choose '''Route''' >> '''Special Route'''<br />
#### This connects the power supply to your cells<br />
### Route design<br />
#### Click '''Route''' >> '''Nano Route''' >>> '''Route'''<br />
#### It is a good idea to specify which metal layers should be used. We usually use Metals 1 to 3 with the C35 process. Specify this in the Routing Control, bottom:top layers section<br />
#### Save design<br />
### Export the design <br />
#### The layout is complete now, and you can export it to GDS2.<br />
#### Click File>>Save>>GDS/Oasis<br />
#### Make sure to load gds.map<br />
#### Save as filename.gds<br />

<div>Results from an experiment to determine the spectral responsivity of the 0.35um process we use quite a lot in this department. May be useful to other users of this process.<br />
<br />
Experiment was conducted on SKED1. 30kOhm load, using 7 hi-power LEDs from Thorlabs. For each LED, power is ramped using an AFG to ensure linearity in response.<br />
<br />
There is no data from the C35 datasheet, but the related opto process gives responsivity data, and this data is overlaid on the SKED1 results (in red). The dotted line is the actual response of the optoC35 response, with a 7th order polynomial fit in the solid line. The blue line is the response of the C35 process as measured using SKED1.<br />
Standard Deviation is of the order of 1mA/W.<br />

<div>=Eagle PCB -> PCBTrain Export Mini How-To=<br />
<br />
==Introduction==<br />
<br />
This Mini Howto explains how to export PCBs designed using [http://www.cadsoft.de Eagle PCB by Cadsoft] into a format suitable for submission to [http://www.pcbtrain.co.uk PCBTrain], a division of Newbury Electronics. PCB Train is normally where we get our PCBs made externally, here at the [http://www.nottingham.ac.uk/eee/ School of Electrical and Electronic Engineering] at the [http://www.nottingham.ac.uk University of Nottingham, UK]. Neither the author, the School nor the University endorses or otherwise any particular PCB manufacturer; this is just personally the one we use, and we know a lot of other people who use Eagle also do too.<br />
<br />
The export process is very easy; this page mainly contains simple instructions, some configuration files (design rules and CAM jobs), and some simple shell scripts to make the export process easy. Note that the configuration files are applicable to all the architectures that Eagle supports (and to its credit, it supports Linux, Windows and Mac OSX at the time of writing); the shell scripts will only work in Linux, and possible OS X (though I haven't tried them). They are just for convenience, they are not obligatory.<br />
<br />
It's also worth noting that CadSoft run a very active [http://www.cadsoft.de/forum EAGLE Forum], which is actually a set of news groups in English and German. If you cannot find the answer to your question either here or in the manuals (click "Program", then "manual-eng.pdf" or "tutorial-eng.pdf") then joining and posting on the newsgroup is well worth a try.<br />
<br />
==The Export Process==<br />
* Load the pcbtrain.dru design rules (on our (UoN) Linux systems you will find this in /home/share/eagle/local_dru/ otherwise right-click). Do this before you do any routing! <br />
* Once your design is complete, save it. <br />
* Start the CAM processor from the Board Layout File menu. <br />
* ''Open a Job''... from the CAM Processor's ''File'' menu. On the Linux systems, the correct directory (beginning /eee/vlsi/eagle/...) will be displayed. <br />
* Depending on the PCBTrain process you want to use, choose from one of the following cam jobs: <br />
** pcbtrain_2_layer.cam <br />
** pcbtrain_2_layer_panelised.cam <br />
** pcbtrain_4_layer.cam <br />
** pcbtrain_4_layer_panelised.cam <br />
** pcbtrain_express.cam <br />
* Click Process Job. This will create a whole load of Gerber files, in a "cam/" subdirectory: <br />
** my_circuit.gtl - Component side (top layer) copper <br />
** my_circuit.gbl - Solder side (bottom layer) copper<br />
** my_circuit.gm1 - Board outline (mechanical) <br />
** my_circuit.gdd - Drill file <br />
** my_circuit.gto - Component side (top layer) silk screen (overlay)<br />
** my_circuit.gbo - Component side (bottom layer) silk screen (overlay)<br />
** my_circuit.gts - Solder side (top layer) solder stop mask<br />
** my_circuit.gbs - Solder side (bottom layer) solder stop mask<br />
* You now have all the files you need. You should zip them up in order to send them to PCBTrain.<br />
* You can check your design using a gerber file viewer such as [http://gerbv.sourceforge.net/ gerbv].<br />
<br />
=Sending Your Design To PCBTrain=<br />
This is relevant only to members of EEE at the University of Nottingham - everyone else should go to [http://www.pcbtrain.co.uk] PCBTrain for information.<br />
<br />
* Create a department order form <br />
** The contact details for PCBTrain are [http://www.pcbtrain.co.uk here]. <br />
** Put on a reference name for your circuit ("my_circuit" in the above example).<br />
** Calculate the price from the [http://http://www.pcbtrain.co.uk/service-selection.php PCBTrain Pricing Table]. <br />
** Get the form signed by someone who has authorisation. <br />
* Send PCBTrain an email, with your attached zip file (!), giving all the information that they require. <br />
** You could use something like [http://http://optics.eee.nottingham.ac.uk/eagle/example_email.txt this] as a template. <br />
** CC Jo Mee and Julie Wells (or anyone in the purchasing office) on the email - ''this step might be optional - confirm''<br />
** As soon as you have sent the email, take down the department order form to the Central Purchasing Office (B89 Coates). <br />
** PCB Train will start to process your order when the department sends through the purchase order (usually 24 hours later).<br />
Your PCB(s) will appear in Engineering Faculty Stores (L2) when it/they arrive.<br />

This Mini Howto explains how to export PCBs designed using [http://www.cadsoft.de Eagle PCB by Cadsoft] into a format suitable for submission to [http://www.pcbtrain.co.uk PCBTrain], a division of Newbury Electronics. PCB Train is normally where we get our PCBs made externally, here at the [http://www.nottingham.ac.uk/eee/ School of Electrical and Electronic Engineering] at the [http://www.nottingham.ac.uk University of Nottingham, UK]. Neither the author, the School nor the University endorses or otherwise any particular PCB manufacturer; this is just personally the one we use, and we know a lot of other people who use Eagle also do too.<br />
<br />
The export process is very easy; this page mainly contains simple instructions, some configuration files (design rules and CAM jobs), and some simple shell scripts to make the export process easy. Note that the configuration files are applicable to all the architectures that Eagle supports (and to its credit, it supports Linux, Windows and Mac OSX at the time of writing); the shell scripts will only work in Linux, and possible OS X (though I haven't tried them). They are just for convenience, they are not obligatory.<br />
<br />
It's also worth noting that CadSoft run a very active [http://www.cadsoft.de/forum EAGLE Forum], which is actually a set of news groups in English and German. If you cannot find the answer to your question either here or in the manuals (click "Program", then "manual-eng.pdf" or "tutorial-eng.pdf") then joining and posting on the newsgroup is well worth a try.<br />
<br />
==The Export Process==<br />
* Load the pcbtrain.dru design rules (on our (UoN) Linux systems you will find this in /home/share/eagle/local_dru/ otherwise right-click). Do this before you do any routing! <br />
* Once your design is complete, save it. <br />
* Start the CAM processor from the Board Layout File menu. <br />
* ''Open a Job''... from the CAM Processor's ''File'' menu. On the Linux systems, the correct directory (beginning /eee/vlsi/eagle/...) will be displayed. <br />
* Depending on the PCBTrain process you want to use, choose from one of the following cam jobs: <br />
** pcbtrain_2_layer.cam <br />
** pcbtrain_2_layer_panelised.cam <br />
** pcbtrain_4_layer.cam <br />
** pcbtrain_4_layer_panelised.cam <br />
** pcbtrain_express.cam <br />
* Click Process Job. This will create a whole load of Gerber files, in a "cam/" subdirectory: <br />
** my_circuit.gtl - Component side (top layer) copper <br />
** my_circuit.gbl - Solder side (bottom layer) copper<br />
** my_circuit.gm1 - Board outline (mechanical) <br />
** my_circuit.gdd - Drill file <br />
** my_circuit.gto - Component side (top layer)<br />
** silk screen (overlay)<br />
** my_circuit.gbo - Solder side (bottom layer) silk screen (overlay)<br />
** my_circuit.gts - Component side (top layer) solder stop mask<br />
** my_circuit.gbs - Solder side (bottom layer) solder stop mask<br />
* You now have all the files you need. You should zip them up in order to send them to PCBTrain.<br />
<br />
=Sending Your Design To PCBTrain=<br />
This is relevant only to members of EEE at the University of Nottingham - everyone else should go to [http://www.pcbtrain.co.uk] PCBTrain for information.<br />
<br />
* Create a department order form <br />
** The contact details for PCBTrain are [http://www.pcbtrain.co.uk here]. <br />
** Put on a reference name for your circuit ("my_circuit" in the above example).<br />
** Calculate the price from the [http://http://www.pcbtrain.co.uk/service-selection.php PCBTrain Pricing Table]. <br />
** Get the form signed by someone who has authorisation. <br />
* Send PCBTrain an email, with your attached zip file (!), giving all the information that they require. <br />
** You could use something like [http://http://optics.eee.nottingham.ac.uk/eagle/example_email.txt this] as a template. <br />
** CC Jo Mee and Julie Wells (or anyone in the purchasing office) on the email - ''this step might be optional - confirm''<br />
** As soon as you have sent the email, take down the department order form to the Central Purchasing Office (B89 Coates). <br />
** PCB Train will start to process your order when the department sends through the purchase order (usually 24 hours later).<br />
Your PCB(s) will appear in Engineering Faculty Stores (L2) when it/they arrive.<br />
