Abstract
A computer-implemented method of routing a circuit design for a target integrated circuit (IC) can include determining a characterization of routing congestion of the circuit design within the target IC and determining a first order cost component of using routing resources of the target IC according to the characterization. The method can include determining a higher order cost component of using routing resources of the target IC according to the characterization and assigning signals of the circuit design to routing resources according to costs calculated using the first order cost component and the higher order cost component. Signal assignments of the circuit design can be output.
