WinSpice Circuit Simulator


WinSpice is a port of Spice3F4 to Win32 systems. WinSpice is ported to run in a window as a native 32-bit application.  It can generate waveform plots to individual floating windows and contains a powerful scripting language (see  the example files included with the executable).

WinSpice contains several enhancements over the original Berkeley Spice3F4:-

WinSpice itself does not contains a schematic editor.  However, 3rd  party schematic editors can be linked to WinSpice.  A schematic editor which uses WinSpice for its simulation engine is available at http://www.5spice.com/.

WinSpice will work under Win95, Win98, WinME, WinNT, Win2000, WinXP, Vista and Windows 7.

Once you have your license key, it will work with future updates up to a future major update and ensure  that any new features will be available.
