In addition to Steve and Scott's comments, I would like to add two more comments: 1) OFTEN, model accuracy is much more important than which simulator you use. 2) If you have a choice of simulators, (you don't with encrypted models) how important is ease of use? For instance, if one simulator costs 50% more, but enables you to get 3 times as much done, do you care?

Usually encrypted models is the deal breaker. Otherwise, Eldo is technically superior to HSPICE in the handling of s-parameters.

With the former being roughly 2 times cheaper than the later, I wonder if it offers a similar performance. I've heard that Eldo has an improved t-line modeling and handles S-parameters in a more advanced fashion. I just never had a chance to work with Eldo, but pricewise it's a big difference for a small company like ours. >> >> Thanks again for your help, >> Julia Nekrylova >> >> 74ze Engineering >> >> __________________________________________________ >> Do You Yahoo!? >> Tired of spam?
