Abstract
A system and method is provided for scan control and observation of a logical circuit that does not halt the operation of the system clock. Thus, all dynamic circuits within the system continue to evaluate and precharge normally. Moreover, the traditional method of placing a multiplexer before the data input of a clocked storage element to perform scan control and observation is no longer required. Consequently, the system and method provide a more efficient manner in which to perform scan control and observation of a logical circuit.
