Proteus Lite is an easy-to-use application for creating printed circuit-board layouts, and is good for hobbyists or students working on small projects. The trial download is basically a pared-down version of Labcenter Electronics' professional PCB application. Proteus Lite creates simple PCBs with 16 copper layers, two silk screens, and four user/mechanical layers, plus an autorouter. Completed designs are suitable for reports, tutorials, or articles. During testing, we found we were forced to register the program before most of the basic functions would work. Also, as the trial version has a 100-pin limitation, we only were able to test Proteus Lite on small schema. Very user-friendly, Proteus Lite is a great program for creating PCBs--but if the trial limitations don't suit you, be sure to check out other programs that aren't as fettered.
