Consider two generated PEX decks. First one describes Metal x option A whereas the second describes Metal x option B.
Option A and option B refer to different metal proprieties like thickness, permittivity, rsheet...
PEX rule deck is obviously coupled to an LVS rule deck. The fact that Calibre checks all decks (LVS + PEX) at once makes the automatic selection of PEX rule decks impossible by internal triggers.
That makes me think about using Calibre DESIGNrev layout peek feature before running Calibre PEX in order to perform automatic selection of the right option...
Ladies & gentlemen...What do you think?
