Abstract

Various embodiments provide for routing a network of a circuit design based on at least one of a placement blockage or a layer-assigned network of a circuit design. For instance, some embodiments route a network of a circuit design (e.g., clock net, date net) by generating a congestion map based on modeling layer-assigned networks, considering (e.g., accounting for) routing congestion based on a placement blockage of the circuit design, or some combination of both.
