Rolf, You are right about the XSpice stuff I just looked again at the help files - but Intusoft seem to have a whole range of models not supported in the Protel simulator, and this is where the conversion of external spice netlists gets difficult if they include advanced extensions (PSpice or Intusoft). At least this has been my experience. I have found a number of models that needed major heart surgery to get them to operate in P99SE. These were generally PSPICE models. The Protel Sim does lack some useful stuff (like Laplace operators). I have only had moderate success. It is some time since I tried to integrate a Intusoft model into P99SE (from memory) but I would hazard a guess that a recent intusoft model using their latest extensions would *not* be easy to port. (I was not successful from memory.) (The XSpice stuff from the stuff I just read on the Intusoft site you referred to seems to mainly add in support for event-driven simulation (useful for mixed-signal stuff. I get the feeling that Intusoft have gone on and added a whole lot of models on top of that.)
