This is quite incompatible with GPL, and in long term we cannot retain it. GPL is compatible with commercial uses, for one. I've found two papers about SPAR ASG, available at <http://citeseerx.ist.psu.edu/viewauth/summary?aid=266025> Steve Frezza's old webpage is available from Internet Archive at <http://web.archive.org/web/20021129131646/http://www.ee.gannon.edu/~frezza/> There I've got his Master's Thesis on SPAR: <http://web.archive.org/web/20031205182032/www.ee.gannon.edu/~frezza/SPAR/frezza-ms-thesis.ps> This should be enough to reimplement SPAR in C++, under a decent license. This is an open task: if there are any takers, you're welcome. Also, if anyone knows of newer research into space partitioning as it relates to automatic schematic generation, it'd certainly help. Ideally, if it'd be something academic with published source code :) Cheers, Kuba _______________________________________________ Xcircuit-dev mailing list [email protected] http://www.opencircuitdesign.com/mailman/listinfo/xcircuit-dev
