Abstract:
A method for timing analysis of a circuit design includes, for each group of one or more instances of a cell of a cell library in the circuit design, determining timing related data for the group according to circuit context of the group in the design. The context includes at least one of a path depth, an output load, and an input slew rate. The determined timing related data are applied to analyze the circuit design.
