Abstract
Aspects of the present disclosure address systems and methods for zigzag detection and handling for integrated circuit designs. Data describing an integrated circuit is accessed. The integrated circuit design comprises a connection path between two or more pins of a net determined based on an initial routing of the net. A zigzag is detected in the connection path based on a local turn density constraint that specifies a ratio of a number of turns to a pathlength that corresponds to zigzagging in the net. In response to detecting the zigzag in the connection path, the zigzag is removed from the connection path by rerouting the net using a routing constraint that defines a maximum number of turns in the connection path.
