What is Circuit Extraction and Parasitic Formats about?

After routing is complete, a circuit extraction tool calculates the parasitic capacitance and resistance of each interconnect based on its exact length and position. This generates data in a standard format like SPF that describes the parasitic values. SPF provides simplified models of interconnect delay and loading, representing the load seen by a gate with lumped RC networks. It also models pin-to-pin delays with RC delays. Detailed SPF shows the actual resistance and capacitance of each interconnect segm
