Abstract:
1. A method of generating a low-skew routing for a network of a circuit design comprising: routing connections between a source and a plurality of loads of the network; determining a delay for at least one routed connection; and accepting the routed connections if the delay of each routed connection is within a skew tolerance range; wherein routing connections further comprises selecting routing resources according to a base cost calculated for each routing resource selected for routing the connections between the source and the plurality of loads of the network, wherein the base cost for each routing resource comprises a delay from the source to the routing resource multiplied by a first tuning factor and an estimated delay from the routing resource to one of the plurality of loads multiplied by a second tuning factor, and a target delay specified as a maximum of lowest delay paths between the source and each of the plurality of loads of the network.
