John,
I'm assuming here that Caesar is aware that eleoctromigration problems are
far worse in lines with unidirectional current flow than with bidirectional
flow. In power supply lines, current is always flowing in the same
direction. In signal lines, it flows in both directions, depending on
whether the line is switching from 0->1 or 1->0. That's why the analysis
tools all concentrate on power supply lines.
