The issue is that we don't define anywhere the rule that the "last" dash separates the name-pinnumber. (See Harry's note above, e.g.:) U102-J1-1, we don't have a rule as to how this separates: U101 pin "J1-1" or "U101-J1" pin "1" Indeed, in your previous case, your suggestion would not do what you want.. since your pinnumbers had a dashes in them. I hope since we've been able to work-around the issue for now, we can live with the "-" issue. Its not really bitten anyone before, and if it becomes an issue, perhaps we can get gnetlist / gsymcheck to flag such things with a warning.
