Method and computer program for detailed routing of an integrated circuit design with multiple routing rules and net constraints

摘要

A method of routing an integrated circuit design includes steps of receiving as input at least a portion of an integrated circuit design including at least two separate routing rules assigned to the same net for routing the integrated circuit design, formulating a single combined routing rule as a function of content of each of the separate routing rules, and generating as output the combined routing rule and a routing rule assignment that assigns the combined routing rule to the net.
