1. A method comprising:
determining power characteristics for a power delivery network of a circuit design based on logic cells of the circuit design, the power delivery network comprises power wires and power staples connecting pairs of the power wires to each other;
removing a first one or more of the power staples from the power delivery network based on the power characteristics;
routing signal wires for the logic cells after removing the first one or more of the power staples, wherein routing the signal wires includes routing a first signal wire of the signal wires in a routing track corresponding to the first one or more of the power staples;
inserting a second one or more of the power staples within the power delivery network based on routing the signal wires to generate an updated power delivery network; and
generating an updated timing model for the updated power delivery network.
