Phew that took a while to follow, here's what I understand the scenario as: There are two sheets in this design. Sheet A has a wire labelled 'WIRE' one end of which is a global label (let's say FOO) and the other end of which has an intra-sheet link element on it. Sheet B has a wire, one end of which has the global label FOO and the other of which is either dangling or has an intra-sheet link element on it. What I would expect and desire would be that if sheet A had no other FOO-labelled net with an intra-sheet link on it, there'd be an ERC error; ditto sheet B. And that the intra-sheet link on A would not be matched by an intra-sheet link on B. So I tried it... You had found a glorious corner case I had not considered. Thank you. I have pushed a small fix to my series which ensures that the expected behaviour (that intra-sheet links do not satisfy one another across sheet boundaries) is restored. (I had failed to check m_SheetPath in my ERC :-) Thank you. D. -- Daniel Silverstone http://www.digital-scurf.org/ PGP mail accepted and encouraged.
