I'm not sure if you answered Rachild's question, Mike.
Rachild, if your company is in the early stages of implementing SI analysis
for board designs, I suggest you have a group of dedicated SI engineers
doing the analysis from pre-layout to post-layout. Have them involved in
the various design stages and work closely with the hardware designers. You
cannot just hand the hardware designers SI tools and expect good results,
for most hardware designers are logic (not analog) experts.

For board designs of moderate complexity it is best to have the hardware
design engineer do the SI analysis. SI is so much a part of the design that
I don't think it is possible to do it well if it is separated. SI affects
timing, trace topology, device selection, and many other things that are
part of what is traditionally considered hardware design. In the past, with
slower devices, a hardware design engineer could ignore SI effects when
looking at these issues, but it is not possible now. The SI software out
there is just another tool that hardware designers use to get the job done.
