At the very least, we also want to be able to use pin numbers. Pin labels are potentially ambiguous, especially for slotted components. But if we could use pin numbers, we could make SPICE netlists with slotted components. I recently asserted this was impossible, but I have been known to be wrong ;-)

This message contains technical discussion involving difficult issues. No personal disrespect or malice is intended. If you perceive such, your perception is simply wrong. I'm a busy person, and in my business "go along to get along" causes mission failures and sometimes kills people, so I tend to be a bit blunt.
