Q: How do I create a part that has a logical pin mapped to two physical pin numbers?
A: To create a part that has a logical pin mapped to two physical pin numbers, you need to define the PACK_SHORT property on the symbol. The PACK_SHORT property enables the shorting of the pins in a group. Consider an example. In a part, abc, a single logical pin, the collector, needs to be mapped to two physical pins such that the pins are shorted. To create such a part, map the C1 and C2 pins in the following way:

Next, define the PACK_SHORT property on the symbol. The definition PACK_SHORT=(C1, C2) ensures that the net name assigned to C1 is inherited by C2 when a design containing the abc part is packaged.

Notice that the logical pins B, C1, and E have pin stubs whereas the logical pin C2 does not have a pin stub. This ensures that C2 is not visible when the symbol is placed in the schematic.
Кто-нибудь пробовал, это с Capture работает?
У меня почему то выдает странное сообщение об ошибке:
#1 Error [ALG0074] Pin "6" found in PACK_SHORT property on part "DA1" doesnt exist on the symbol. You need to specify a valid pin.
#2 Aborting Netlisting... Please correct the above errors and retry.
В свойствах элемента есть PACK_SHORT=(6,7), причем выводы эти для корпуса SOIC-8, и оба там присутствуют.
