A method and apparatus for determining the propagation delay of a selected net in a circuit design is described. In one exemplary embodiment, a selected net is received, where the selected net includes a plurality of characteristics that represent the physical and/or parasitic parameters of the net. A net is a set of one or more wires that connects a set of circuit junctions between a pair of endpoints of that net. In addition, a simulation is performed on the selected net using the plurality of characteristics. The circuit design system computes the propagation delay for the selected net based on the simulation and makes available the propagation delay of that net. The propagation delay for a net is the delay for a signal traveling between the endpoints of the net. |
