XSpice itself is pretty general, so long as you have the *correct*
model, it should do most jobs. If you doing cmos ic rf, then there may
be an issue, as the basic XSpice does not directly support the parasitic
parameters (AS AD NRS NRD) typically calculated in say, HSpice, by hdif.
This could have a 2.5Gz oscillator coming out at 1Ghz for example.
However, I am aware of one XSpice based simulator that does not have
that particular problem:-)
SuperSpice, a very affordable Mixed-Mode
Windows Simulator with Schematic Capture,
Waveform Display, FFT's and Filter Design.
