CGen Coupon Generator options
PCB – Impedance coupon generator
CGen Coupon Generator reduces the time-consuming process of creating impedance coupons manually to just a few minutes, adding powerful new features that give coupon generation new levels of control and flexibility.
CGen PCB Coupon Generator is an automatic impedance coupon generator that allows you to create a controlled impedance test coupon from scratch or import finished stacks from Speedstack PCB and Speedstack Si or structures from the Polar Si8000 and Si9000 field solvers.
CGen Si (Beta) incorporates all the features of CGen and adds
insertion loss coupon capability. Please note designs for insertion loss
coupons are still being fine tuned by OEMs and final adjustment of
launch and via structures may still be required. If in any doubt -
please check with your design authority.

How will CGen benefit you?
Automatic standalone impedance coupon generationCGen provides a clear and intuitive step by step process for creating your coupon; you simply choose the number of layers, specify board symmetry, identify each layer type and then add impedance structures as required:
Choose the coupon style - the coupon is displayed interactively in the Coupon View pane
Importing stackups from Speedstack
CGen Coupon Generator can also take impedance controlled stackup information directly from Speedstack PCB or Speedstack Si.
CGen automatically generates the appropriate impedance test coupon containing all the required PCB controlled impedance transmission line structures, reducing what is normally a time consuming process to minutes.
Importing structures from the Si8000m or Si9000e
CGen is fully compatible with the industry standard Polar Si8000m controlled impedance field solver and the Si9000e frequency dependent, lossy line GHz field solver.
Simply copy and import your finalized structure from Si8000 / Si9000 to add the structure to the selected layer.
Replacing scripted coupon generation
CGen 2012 replaces time consuming manual or scripted coupon creation with a simple four-stage process:
Power users familiar with scripting can also import third party XML stack files
Reducing errors in coupon generationIn addition to being time consuming, manual coupon generation may be prone to errors, especially where complex structures are involved, and even if you use a scripted solution, not all scripted routes to coupon generation create the more complex coplanar strip or waveguide structure types.
One of the most critical areas of coupon design is matching the test probe to the coupon interconnect. CGen Coupon Generator allows you to pick from a list of the industry's most frequently used IP probes for CITS impedance test systems. The interconnect for the chosen probe is then automatically engineered into the artwork.
do I use the Coupon Generator?
CGen includes powerful time-saving features
Create your impedance controlled stackup in CGen itself
Using CGen you can create your coupon from scratch, defining symmetry, the number of layers and layer type and then adding impedance structures as required.:
Import finished stacks from Speedstack
Export your completed stack from Speedstack and import into CGen, choose your probe, and generate your preferred coupon style. CGen Coupon Generator will then create RS274X and a drill file for export.
Import your finished structure from the Si8000 / Si9000
From within the Si8000m / Si9000e copy the finalized structure into CGen onto the selected layer; you can then manually enter
line widths into the structure. Power users familiar with
scripting can also import XML data directly.
