Abstract: A method for operating a data processing system to simulate a circuit that includes a plurality of circuit devices connected by interconnects. A layout description of the circuit is provided in which the devices are connected by interconnects. Each interconnect is associated with a line definition that includes a physical description of an interconnect between two of the circuit devices and a simulation model to be used in simulating the interconnect during simulations of the circuit. The line definitions are user selectable from a list of available line definitions. A circuit netlist is generated by reading physical interconnects from the layout. At least one of the interconnects is replaced by a plurality of transmission line devices, each device being associated with the simulation model included in the line definition. The circuit is then simulated using the netlist.
