摘要
Some embodiments of the present invention provide techniques and systems for determining and using margin values. An arrival time at an output pin of a logic gate can be determined. Next, required times at the output pin of the logic gate can be determined. Each required time can be associated with a timing end-point in a path-group, affected by that pin. The system can then determine a first set of slack values at the output pin of the logic gate by computing a difference between the required times and the arrival time. Next, the system can determine a set of margin values at the output pin of the logic gate by computing a difference between the first set of slack values and a second set of slack values at the timing end-points in the path-groups. Next, the system can use the set of margin values to optimize the logic gate.
