    摘要: A scannable pulse dynamic logic gate may include an evaluation network that evaluates dynamic inputs in response to assertion of an evaluate pulse. The evaluate pulse may be generated from a clock signal such that it is shorter in duration than the clock signal. During a normal mode of operation, when the evaluate pulse is asserted, the evaluation network may discharge a dynamic node depending on the state of the dynamic inputs. The dynamic node may then drive output device(s). When the evaluate pulse is deasserted, the dynamic node may be precharged. The gate may also include scan input devices, which, during a scan mode of operation, may load scan input data onto the output node in response to assertion of a scan master clock. A storage element of the gate may receive and capture a value of the output node in response to assertion of a slave scan clock.

    摘要: A system and method for reducing power consumption within clock distribution on a semiconductor chip. A 4-phase clock generator within a clock distribution network provides 4 non-overlapping clock signals dependent upon a received input clock. A reduced voltage swing clock generator receives the non-overlapping clock signals and charges and discharges a second set of clock lines in a manner sequenced by the non-overlapping clock signals. The sequencing prevents a voltage range from reaching a magnitude equal to a power supply voltage for each of the second set of clock lines. In one embodiment, the magnitude reaches half of the power supply voltage. The reduced voltage swing latch receives the second set of clock lines. The reduced voltage swing latch updates and maintains logical state based at least upon the received second set of clock lines.

    摘要: Systems and methods for testing ASIC and RAM memory devices are disclosed. The method comprises determining a signature map of valid power supply current values for a known good microcircuit wherein each valid power supply current value is measured at a fixed level of power supply voltage and corresponds to a unique test input stimuli pattern applied to the known good microcircuit. The signature map of power supply current values is stored in an electronic memory (300). The test input stimuli patterns are then applied to an unproven microcircuit (330) and the power supply current of the unproven microcircuit is forced to the levels stored in the signature map by a current supply (360) while the voltages across the power supply inputs of the unproven microcircuit are measured by a voltmeter (340). The measured power supply voltages for each power supply current value are then compared to the fixed voltage supply level used to test the known good microcircuit. The unproven microcircuit is faulted if any measured power supply voltage of the unproven microcircuit differs substantially from the fixed power supply voltage applied to the known good microcircuit.
