Abstract
A system and method updates a clock tree based on skew values of the circuit design. The clock tree is updated by obtaining a circuit design that includes circuit elements and a clock tree. The clock tree includes clock sources and clock sinks. Data path slack values for the clock tree are determined based on the clock sources and the clock sinks. Further, clock arrival values for the clock tree are determined based on the clock sources and the clock sinks. A first total local skew value of the circuit design is determined based on the data path slack values, and the clock arrival values, and updating the clock tree based on the first total local skew value.
