Sounds like we have similar backgrounds and motivations. I have a project started along these lines, but I haven't had time to work on it for the last few months. http://www.ece.arizona.edu/~edatools/ Project page EDA Tools Projects: An Open-Source Platform for Front-End IC Design cdp_tut01-a1.zip cdp_tut01-a1.tar.gz The goal of this project is an easily-learned, universal, open-source, circuit design platform that will allow IC designers to use whatever tools they want for design entry, simulation, and display of results. The platform should provide a simple GUI, basic services such as storage of tool setups, and should define a simple, standard interface for each class of tool. Most of the work will be in documenting the design and construction of the platform, using a simple scripting language ( Python ) and GUI toolkit ( Qt ) so that others may easily follow the pattern and extend the platform to support new and more varied tools. ------ Take a look also at the MyHDL link from the main page. This is a similar effort for digital design. Mine is mostly analog. The discouraging thing about the EDA tools situation is that no matter how loudly design engineers complain about the poor quality of the proprietary tools they are using, there is very little interest in participating in an open-source project. They just can't see how it would ever do what their expensive tools do now. There is a similar lack of interest in the academic community. None of this is likely to lead to publications in scholarly journals. -- Dave -- http://mail.python.org/mailman/listinfo/python-list
