Abstract
A system and method for scan testing an NCDL and latches controlled by the NCDL is presented. The NCDL is controlled by control logic, a switch is used to control the latches by a clock signal that is not controlled by the control logic. A controllability circuit provides test vectors to, and controls, the NCDL. The outputs of the NCDL are observed by an observability circuit that captures the outputs of the NCDL.
