Thanks Dick, I have figured it out, and it agrees with what you are saying.
I am building 'power ports' in the same way you are. I am doing a Schematic ERC, but primarily interested in connectivity (no IN's to OUT's etc). Pin types can be 'power in' or 'power out'. Power ports must comply with at least 2 rules: 1. The pin must NOT be drawn. 2. The pin type must be 'power in' or 'power out' else, the net list will not connect correctly. I really do not want to specify a 'power out' pin to drive the net of 'power in' pins. It just seems like a lot of trouble. So I end up with Schematic ERC - "Warning power pin in not driven". Then, checking the manual, I found the Schematic ERC options. Alas, it seems none of these options would permit the power ports without a single 'power_out' pin type in the net. So I am going fine. I will likely allow the ERC warning to remain, but am loathe to do so. Thanks for confirming this stuff, ...Jim H. ----- Original Message ----- From: dickelbeck To: [email protected] Sent: Tuesday, September 01, 2009 10:46 AM Subject: [kicad-users] Re: placing Power Ports When you say 'power port', can I assume you mean something like a ground symbol or a symbol for +5V which you make yourself? If so: I would check the help manual for special requirements on parts that are to be sources and sinks of power. (parts with a single pin.) I have a personal library with several such parts, and although I cannot recall exactly, I know I was referred to the manual when I asked a similar question 2-3 years ago on this list. There was something special about building these parts, but I don't remember whether it was PIN name or what.... I just know it is recorded on this list, and also in the manual. What you want, CAN be done, as I have a library full of such components. Dick
