Our codes feature examples of circuit simulation algorithms and back end layout tools such as extraction/design rule checkers and netlist comparators. Most are available for immediate download but there are also more powerful codes that will soon be available through a yearly membership and a nominal fee.
The idea behind the software is to provide low-cost tools that can be used for small-medium sized circuit blocks in the intermediate build phase. It is often not necessary to use the top-of-the-line tool offerings by the big players in the industry for such applications.
The circuit simulation algorithms are described in our book "Analog Circuit Simulators for Integrated Circuit Designers"
