Abstract

An apparatus and method of scanning a dual edge-triggered flip-flop with scan capability includes a first scan slave element capable of capturing data on a positive edge of a clock signal; and a second scan slave element capable of capturing data on a negative edge of the clock signal. An apparatus and method of scanning a dual edge-triggered flip-flop with scan capability includes a scan slave element capable of capturing data on either a positive edge or a negative edge of a clock signal; wherein a control signal determines whether the scan slave element captures data on the positive edge or negative edge of the clock signal.
