WinSpice Circuit Simulator

Welcome to the Frequently Asked Questions (FAQ page). Below, we have tried to answer the most common questions visitors to this our Web site may have. If you find that your question is not answered on this page, please contact me.

Q: Is WinSpice compatible with Spice2 netlists?
A: When you open a Spice2 netlist, a preprocessor converts the Spice2 directives into a netlist plus a set of Spice3 commands which emulate the operation of Spice2 which has a preset order of analysis. Most directives are supported - let me know if you find any Spice2 netlists which are incompatible.

Q: Does WinSpice work work with Win95/98/ME/NT/2000/XP/Vista?
A: As far as I know, yes. Its use of the Windows API is minimal and it uses no special DLLs, controls etc. I know that it runs on Win2000 and WinXP because I use these two OSs daily.

Q: Does WinSpice have any device, memory or node limitations?
A: WinSpice has no limitations at all - I have been sent enormous circuits which have eaten up over 300Mb of memory without a hiccup.

Q: I keep getting a nag message appear. How do I get rid of it?
A: This message only appears if you use any non-Spice3 features that I have added to the original Spice3 core. If you restrict your use to Spice3 features and model parameters, you will not see the nag screen. If your circuit seems not to have any non-Spice3 features in it, it is likely that any imported device models will be using PSpice or HSpice syntax. You can prevent the messages altogether by registering the program whereupon I will send you a license key file. If you are using WinSpice for professional purposes, you must register.

Q: Is WinSpice available for Linux?
A: I haven’t tried it myself, but I know that it works under Wine. I am looking into creating a version of WinSpice which runs natively on Linux using an open-source, cross-platform windows library. This should mean that the Windows and Linux versions will operate almost identically on both platforms. A Linux version will be available in 2010.
