发明名称 Method and system for clock skew independent scan register chains
摘要 A method and system for clock skew independent scan chains. In one embodiment, a method comprises connecting a plurality of mux-D scan registers in a chain configuration, wherein a first mux-D scan register of the plurality is associated with a first clock network, and a second mux-D scan register of the plurality is associated with a second clock network. The plurality of mux-D scan registers have a scan mode. The first mux-D scan register and the second mux-D scan register become clock skew independent by controlling a scan-enable signal and a clock signal.
