Abstract
Generating a design of an integrated circuit by analyzing a physical design of an integrated circuit by determining, for a pin of a circuit of the integrated circuit, that a candidate timing constraint for signal arrival time at the pin is later than a current timing constraint for signal arrival time at the pin, determining that a slack value associated with the current timing constraint has a greater negative value than a predefined negative slack threshold value, determining that the current timing constraint is within a user-defined range of signal arrival time values associated with the pin, determining that the candidate timing constraint is earlier than a latest-allowable signal arrival time at the pin, setting the current timing constraint equal to the candidate timing constraint, and generating a revised physical design of the integrated circuit that incorporates the current timing constraint.
