It seemed to me that P-CAD 2004 will be the last of P-CAD line from Altium (used to be Protel). Altium has ended the support for the low-end Circuit Maker and I guess P-CAD will also die soon and they will move to Altium Designer as well. Then there is ORCAD. We use PSpice 10.3 for circuit simulation only. The ORCAD layout should also be quite good. I am not so familiar with the various layout packages. What are the commonly used layout tools for the medium end (no high-speed / high density requirement) for business use? For personal/SOHO use, Eagle seems to be the choice of many PIClist members.
