This paper describes the design and hardware results of a scannable pulse-to-static conversion register array for self-timed circuits. The circuits include a self-timed control circuit and a 64-bit register array, both designed utilizing self-resetting CMOS (SRCMOS) circuit techniques. The self-timed feature of the control block allows it to require only one system clock input. The evaluation, reset, and write-enable controls are all generated within the control macro. The register array is a level-sensitive scan design, which is compatible and complies with SRCMOS test modes. This type of register array can facilitate the synchronous/asynchronous interfaces, pipelined operation, power management, and testing of advanced digital systems employing a mixture of static and dynamic circuits to achieve low power and high performance.
