WinSpice 1.0

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.
WinSpice contains several enhancements over the original Berkeley Spice3F4:-
better compatibility with Spice2 and PSpice circuit files, such as handling for POLY statements in nonlinear sources
support for PSpice-style libraries
manual and a simple tutorial, both in Word for Windows 2 format
hundreds of bug fixes (most of the memory leaks have been plugged!)
three versions of the BSIM3 model, JFET2, BSIM4 device models
zoomable plot windows
the EKV MOSFET model from Ecole Polytechnique Federale de Lausanne (EPFL)
parameterised subcircuits
