Clock gate placement with data path awareness

Abstract:

Electronic design automation systems, methods, and media are presented for clock gate placement with data path awareness. One embodiment involves accessing a circuit design with a clock tree, clock gates, and an initial movement area. A set of positions for a set of data path connection points associated with the data routing lines are identified, along with an expansion direction from the initial placement position toward the set of positions for the set of data path connection points, and the initial movement is expanded to consider additional placement options for the clock gate based on the data path connection points.
