Abstract:
A method for identifying and removing redundant signal paths includes determining whether a given input to a logic circuit is coupled to both an input of a cone of logic of a data input of a clocked state element and a clock gate circuit that is coupled to disable a clock input to the clocked state element. The method may include removing the given input from the cone of logic such that the given input is no longer coupled to the input of the cone of logic responsive to determining that the given input is coupled to both the input of the cone of logic and the clock gate circuit. The method may include preserving the given input to the clock gate circuit such that the given input continues to be coupled to the clock gate circuit after being removed from the input of the cone of logic.
