摘要
Methods and systems for determining a numerical delay model based on one or more discretized delay models are described. A discretized delay model is a delay model in which the delay behavior is represented using a set of discrete data points of delay behavior. A numerical delay model is a delay model that can be used by a numerical solver to optimize a cost function. In general, computing delay using a numerical delay model is significantly faster than computing delay using discretized delay models. This performance improvement is important when optimizing a design for various metrics like timing, area and leakage power, because repeated delay computations are required in circuit optimization approaches.
