Problem

In EDI fixACLimitViolation command to fix EM violation. This repairs associated violations associated with electromigration on signal wire properly by buffering to reduce the capacitance on the net in order to fix the violation.

But, sometime these violations are not reported in EDI due to improper modeling and the limitation of setting extraction mode to detailed. So, user does not want to use this EDI capability and rather wants to take input from sign-off tool to fix them on EDI by re-routing these wires with wire-widening.

Is there a way to fix fix EM violations reported by sign-off tool in EDI?

Solution

One can use below script to fix electromigration violations using non-default rule and then re-route using eco route.
