>As far as having a tool for doing schematics and small >layouts, Eagle has a "free" version and various levels >of "paid" versions depending on what you need. You may like to look at the demo copy of Orcad. The CD comes with demo versions of PSpice, capture and Layout, which are not time limited as far as I can see, but are definitely net and pin limited. There is also a demo version of Specttra router, but cannot save the result. Another possibility for PSpice is to get the Linear Technology Switcher Cad package, which although aimed at doing switching regulators, some on this list have reported that it works admirably as a PSpice program for anything.Not tried it for that myself though. _______________________________________________ http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
