Also of note... I've got a bunch of tools in glscopeclient and libscopehal/libscopeprotocols for NRZ/PAM4 signal generation, channel emulation, de-embedding, equalization, clock recovery, eye patterns, etc. Might be worth pursuing some kind of integration to develop a full channel design/simulation tool kit in KiCAD down the road? I have an IBIS parser already but haven't built a full IBIS simulator yet. It's on the to-do list though. All of these tools are 3-clause BSD so license compatible with KiCAD.
Ideally I'd like to integrate with an EM solver to extract a S-parameter model of a PCB channel as well, so I can just click on pads of a board to set up ports, configure a frequency sweep, then shove that into a time domain model. Here's a quick demo of some of the channel design tools: https://www.youtube.com/watch?v=tgxtSVG4y_E On 8/30/21 3:24 PM, Reece R.
