Abstract
In certain embodiments, a method includes the following steps. An engineering change order (ECO) is for fixing a violation of a target constraint on a target netlist of an integrated circuit. A constraint on a related netlist of the integrated circuit is identified. The identified constraint is adversely affected by fixing the violation of the target constraint. A processor concurrently modifies the target netlist to fix the violation of the target constraint and modifies the related netlist to prevent violation of the adversely affected constraint.
