Abstract
One embodiment of the present invention includes a method for updating timing parameters after a circuit design change. The method includes, prior to the circuit design change, deriving a value for a first timing parameter based on a signoff timing analysis of a timing arc, and a value for a second timing parameter based on a quick timing analysis of the timing arc; and obtaining a first transition time based on the quick timing analysis. The method further includes, after the circuit design change, deriving a value for a third timing parameter based on the quick timing analysis, obtaining a second transition time based on the quick timing analysis, and deriving a fourth value for a fourth parameter based on the quick timing analysis, wherein the fourth parameter is based on the first, second, and third parameters and on the first and second transition times.
