M.I.T. original sources

 

FastCap and FastHenry M.I.T. source code distribution

This is the M.I.T. link for FastCap and FastHenry Unix source files distribution.

 

MIT CAD group

This is the direct link to the M.I.T. CAD group, where FastCap and FastHenry were developed. Throught this link you can reach the pages containing the original docs and the papers presenting the algorithms implemented in the software.

 

Software interfacing FastFieldSolvers tools

 

Whiteley Research

Whiteley Research offers a commercial graphical editor and design tool for integrated circuit mask layout, schematic capture, and much more, and a companion circuit simulation tool. Parasitic extraction is available through FasterCap, FastCap and FastHenry.

 

Free circuit simulators

 

LTSpice IV

LTSpice IV is a free, analog / digital Spice-based simulator for Windows with schematic entry and waveform post-processor from Linear Technology. Very useful free tool to run circuit simulations on the results of your field solvers extractions.

 

ngspice

Ngspice is an open-source (BSD license), free, multi-platform (Windows, Linux, MacOS), analog / digital Spice-based simulator. It is an evolution of the original Berkeley SPICE3F5, integrated with XSPICE (for mixed-signal simulation), and including TLCSpice (a TCL/TK interface).
Ngspice is also integrated in the free gEDA suite of Electronic Design Automation tools available for Linux and MacOS.

 

QUCS

Qucs is a promising open-source (GLP license), free, multi-platform (Windows, Linux, MacOS) circuit simulator. Qucs provides a GUI for schematic entry and for showing simulation results in various types of diagrams. It supports DC, AC, S-parameter, noise and transient analysis is possible. It allows mathematical equations and use of a subcircuit hierarchy (with parameterised subcircuits) are available. Qucs can also import existing SPICE models.

 

Free Math packages

 

SciLab

Scilab is free and open source software for numerical computation providing a powerful computing environment for engineering and scientific applications. It is a very valid replacement for Matlab.

 

Maxima

Maxima is an open source, free system for the manipulation of symbolic and numerical expressions. It is the right companion for SciLab.
