Argh. > Yes that is true. LTSpice is one of the best free SPICE circuit simulator. But they do not provide as many libraries as the commercial offerings like PSpice or others. I used PSpice and Saber (not using the spice engine) and both are quite expensive. Now I occasionally use LTSpice for simple circuits. I still have access to Saber license at work but I seldom use it for simple circuits. -- Xiaofan http://mcuee.blogspot.com -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
