Abstract: A dynamic incrementer, implemented in the Self Resetting Complementary Metal Oxide Semiconductor (SRCMOS) circuit family, which internally performs single rail calculations and which generates the dual rail result using a strobing technique. The carry-lookahead function is implemented with an OR tree using the complement input signals, resulting in a very fast and economical incrementer.

Abstract: A computer-based method automatically synthesizes, optimizes and compiles high performance control logic using SRCMOS LOGIC ARRAY MACROS, abbreviated as SLAMs.

Abstract: A logic circuit family implements self-resetting CMOS logic array macros (SLAMs) which include a plurality of inputs to which a plurality of data input signals can be applied; a plurality of input buffers coupled to receive the input signals from the inputs; a NOR circuit coupled to receive the outputs of the input buffers and a pulsed logic timing signal synchronized within a predefined window with the arrival of the data input signals; an output buffer coupled to receive the output of the NOR circuit; and an output at which a data output signal is produced, with the output signal being a logical NOR of the data input signals; and with each of the NOR circuit, the plurality of input buffers, and the output buffer optionally having a separate reset input to reset it to a standby state. The SLAMs address the very high pressure on the performance of both control logic and control logic design systems.

Abstract: A low-power pulse-to-static conversion latch circuit is disclosed. The circuit includes self-timed control and an n-bit latch array both designed utilizing self-resetting CMOS circuit techniques. The self-timed feature of the control requires only one system clock input. The evaluation, reset and write-enable controls are all generated within a control macro. The latch is level sensitive scan design (LSSD) compatible and complies with self-resetting CMOS (SCRMOS) test modes. Use of these latches facilitates the synchronization, pipelined operation, power-management, and testing of advanced digital systems employing a mix of static and dynamic circuits to achieve high performance.

Abstract: A high performance register that can be used as a pipelined register in logic chips that are designed using a pulsed logic methodology is described. The register features minimal setup time, pulse catching and pulse launching. The register circuitry complies with and implements a circuit-level test methodology for pulsed logic that features the ability to inhibit the reset of pulses, to force resets and to operate the circuits in a pseudo static mode. The register also complies with the level sensitive scan design (LSSD) methodology. Also described is a state-holding static master-slave register that complies with a pulsed logic design methodology, the register exhibiting an automatic power reduction feature and a simplified modular register bit design which can easily be adapted to either static domino or pulsed logic. The register is also LSSD compliant. Also described is the means and method for allowing static transmission gate input registers to comply with the static evaluate test mode.

Abstract: The invention provides a technique, given a netlist containing a description of the terminal connections and the length and width of each device in a circuit, for automatically producing a layout for each device in that circuit.

Abstract: A pulsed logic circuit test methodology and circuitry therefor are disclosed. The methodology and circuitry allow the inhibiting of reset pulses, the ability to force resets and the ability to test the circuit in a pseudo-static mode of operation.
