Welcome to the WinSpice Web site.
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).
This is very much work in progress - I want to add a proper windows help file, schematic entry and an improved windows interface at some point in the future. However, it contains several enhancements over the original Berkeley Spice3F4:-
better compatibility with Spice2 and PSpice circuit files, such as handling for POLY statements in non-linear sources
support for PSpice-style libraries
manual and a simple tutorial, both in Word for Windows 2 format
numerous bug fixes
three versions of the BSIM3 model, JFET2, BSIM4 device models
zoomable plot windows
most of the memory leaks have been plugged!
