I was recently searching for some open tools to get started with VLSI Layout design and also for simulating them with varying features. Listed below are the options that I found:
- Electric – from Static Free Software
This is a Java based tool and has Schematics, Layout and Simulation together into a single file.
- Alliance – from ASIM department of LIP6 laboratory of the Pierre et Marie Curie University (Paris VI, France)
This a complete CAD tool but I am yet to evaluate it.
- Microwind – This is one of the most renowned tools but I am still unable to make it work, hope that once I get through making it work would post more on it.
