Hi all, I would like to suggest to anybody interested in Xspice or simulation in general to have a look at Circuitmaker which I think was a Microcode product later taken over by Altium. I suppose there is no support from Altium for this good software. Circuitmaker has a Xspice engine and uses the same Simcode language which Protel99 uses for modelling its digital devices. Its greatest plus is a very quick learning curve.BTW, the simulation of the inverter discussed in this thread gave me satisfactory results with Circuitmaker. Its manual gives good information on Xspice models and how to solve convergence problems in a spice simulation.
I am not sure about now but a search on google for its evaluation version (the last version was Circuitmaker2000) should be enough.
