As sort of an extension to heterogeneous symbols I wonder how I can make generic symbols, consisting of a set of "sub"symbols, e.g. a relay coil and several types of contact arrangements like SPST and SPDT, all as separate, little symbols. In my design I would then select the appropriate subparts and assemble a particular arrangement, assign the same refdes to them (probably suffixed by "a", "b", "c" or similar in lower case). So far this is simply possible with gschem AFAIK. BUT: relays (to stick to the example) come in (very) many different physical shapes and layouts, each with its own, vendor dependent pin numbering scheme. Therefore, it would be nice to have the possibility to define the pin numbers in the instantiation at the schematic level rather than the fixed pin numbers as defined in the symbol (class level). The slot mechanism is not intented nor useable for this. I have not found any way to promote the pinnumbers to the instantiation or other ways to achieve this. Suggestions more than welcome! thank you, hans
