    >What does "conflicting strength specification" mean ?
     
     I would guess that it means specifying a 0 drive strength on a pullup
     or a 1 drive strength on a pulldown. For example:
     
     pullup (weak0) p1(w);
     
     This will produce a warning in XL and NC, and drive w with pull1 (ignoring
     the weak0 specification). The warning in NC actually calls this a
     conflicting drive strength, which doesn't prove anything except that
     another implementor came to the same conclusion that I did about what
     this term was intended to mean.
