Auto generate PCB impedance coupons with Speedstack & CGen
Whilst Si8000 and CGen are great for low layercounts with a few impedance structures, using Speedstack transforms the process of impedance coupon generation. Using a sample 10 layer build, this 9 minute video takes you step by step through coupon generation and validation with Speedstack and CGen - finishing with the export of Gerber, Drill files and impedance test files.
