I guess I should have said PADs which is owned by Mentor. Hyperlinx has a direct import from PADs, so the two work together well. They have a module called LineSim which is for pre-layout. In that case you enter all the information directly and the layout file is irrelevant. They have another Package called BoardSim that you can import the PADs and other type layout files into. I think its main advantage is ease of use.

Joel- are you wanting to use hyperlynx b/c you deal with a lot of mentor files or board files in general? I have not used hyperlnyx but you might want to also check out a few other tools like speed2000, and another company, Sigrity. Hspice might also be a thought. if your needing to implement actual layout files in your simulations, then your going to need to know the importing capabilities of each tool. I have personally used hspice, cadence's specctraquest, and APSIM. regards, Bill Joel Brown wrote: > I have been looking at Mentor Hyperlinx since we need some signal > integrity tools for PCB layout.
