Hi Jecel,
thanks for your input the Alliance tools look funny unixish and also quite complete, so why not using them. Also the page mentions a process library. The ebook on the tools gives a good overview, thanks! http://www.cc.toin.ac.jp/sc/palacios/openbook/vlsie.pdf
The home page of Alliance is here: https://www-soc.lip6.fr/equipe-cian/logiciels/alliance/
The source is there: git clone it. https://www-soc.lip6.fr/git/alliance.git
Thanks,
Ludwig

Thanks, Luke, for mentioning Alliance. I had forgotten about it, but now have read this book which has a nice example of using it:

The typical unix command line style reminds me of the old Berkeley tools. I am sure this makes makefile fans very happy (just as vi-like commands in Magic is "intuitive" to some people).
This list of free VLSI tools seems reasonably complete:

Besides standard cells, I have studied other design methods in the past such as PPL (Path Programmable Logic from the University of Utah) or Gate Matrix from Bell Labs.

I don't currently have access to ACM and IEEE online stuff, but these references might be useful to some people. These are not open source tools, however. I actually bought a copy of the PPL tools back in 1990 but can't use them due to a silly protection scheme. But the ideas might be worth looking at.
