I'm looking for some software for modelling signal propagation/integrity on high-speed digital PCBs. Can anyone suggest something? This is for hobbyist use so something free/cheap would be preferable. I'd prefer Linux if possible, or Windows as a second choice.
Or should I just be using Spice? My analog knowledge is currently near-zero, so I think I'd find this difficult, but I'd be willing to give it a go.
All suggestions gratefully received -
Rick
