Routing method for integrated circuit and related integrated circuit

摘要

A routing method is illustrated. One exemplary embodiment of the routing method includes: determining a signal path between a signal source and a corresponding receiving terminal according to a routing structure of a system power mesh; determining a routing structure of an independent power mesh that is independent from the system power mesh according to the signal path; and performing a routing process according to the determined routing structure of the independent power mesh and the signal path. The system power mesh and the independent power mesh are respectively coupled to different voltage sources.
