It is difficult to find a good algorithm for this. The latter case
above can be easily understood as the last "connect/resolveto" is a
strict subset of the previous one and therefore more specific (and
the prefered choice), if on the other hand you have:
connect cmos1 cmos2 cmos3 resolveto cmosX;
connect cmos0 cmos1 cmos2 resolveto cmosY;
- and you are connecting cmos1 and cmos2 but there is no rule
specific cmos1/cmos2 rule, which of cmosX or cmosY do you use.
Some extra information may be required if you don't want to just
take the first (or last) match.
