From: "Sergey Stepanov (no DOT such DOT process AT gmail DOT com) [via geda-user AT delorie DOT com]" To: geda-user AT delorie DOT com Content-Type: text/plain; charset=UTF-8 Reply-To: geda-user AT delorie DOT com Looking through the documentation, I found that there is one feature of pin, named pintype: > The pintype is an enumerated type: > NORMAL PIN = 0 > BUS PIN = 1 unused In all symbols in the gEDA distribution, and also in gedasymbols.org cvs, the pintype attribute set to 0, and 1 (BUS_PIN) is not used at all (as stated in documentation). I looked through the git history, but this did not make things clearer: there's no clear description, what is it for. It remains unused since its introduction in 2002. Is there any purpose (current or future) for such pins? The only difference I've found is that the bus pin is a bit thicker (and, of course, there is some actions in code dealing with it).
