Abstract
Various embodiments provide for layer assignment of a network of a circuit design based on a resistance or capacitance characteristic, such as a resistance/capacitance characteristic associated with a layer, a wire, or a via of the circuit design. In particular, various embodiments consider a resistance/capacitance characteristic of a layer, a wire, or a via of a circuit design to determine a set of layers for routing one or more networks of the circuit design, which can enable some embodiments to route the networks on the layers within a certain range that has very close resistance/capacitance (RC) characteristics, and can permit routing each network on layers having the smallest RC characteristic difference.
