    摘要: A method and system for system for clock skew independent scan chains are disclosed. 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.

    摘要: A method for implementing a single file format for power-related information for an IC comprising: providing a circuit design in at least one design file in a non-transitory computer readable storage device; providing power-related design information in a file in the computer readable storage device that is separate from the at least one design file and that specifies multiple power domains within the circuit design, each power domain including one or more design object instances from within the circuit design and that specifies multiple power modes each power mode corresponding to a different combination of on/off states of the multiple specified power domains and that specifies isolation behavior relative to respective power domains; and using a computer to add power control circuitry to the circuit design that implements the power domains and power modes and isolation behavior specified in the power specification information.
