摘要： A method of designing a logic circuit includes providing a leaf cell having at least one transistor. The leaf is suitable for use as a 1-cell or a 0-cell in the logic circuit. A first array of abutting leaf cells is tiled using at least one 1-cell and at least one 0-cell to define at least one logical expression by the relative positions of the array cells. Length optimized interconnects are added to the array. Each length optimized interconnect terminates at a last leaf cell in the array to which the interconnect makes contact. The leaf cell may be a floating leaf cell in which any pair of abutting cells are electrically isolated from one another until the length optimized interconnects are added to the design. The leaf cell array likely includes a set of rows and a set of columns in which the leaf cells in each row and the set of columns each correspond to an input of the logical expression.

摘要： A dynamic node keeper device for a dynamic strobe circuit is controlled by the signal at the intermediate node, that is, the signal at the output of the strobe component. By controlling the dynamic node keeper device through the strobe component output, the keeper device is active or conductive only when necessary to protect against noises in the pull down network for the strobe circuit. At all other times in the course of operation of the dynamic strobe circuit, the dynamic node keeper device according to the invention is nonconductive or inactive. Thus, the dynamic strobe circuit according to the invention reduces power consumption.

摘要： Several local clock buffers are disclosed, each including an input section and an output section. The input sections are substantially identical, and include control logic and gating logic. The control logic produces a gating signal dependent upon multiple control signals and a time-delayed global clock signal. The gating logic produces an intermediate clock signal dependent upon the global clock signal and the gating signal. The output section produces at least one local clock signal dependent upon the intermediate clock signal. In one embodiment, the output section produces a first local clock signal dependent upon the intermediate clock signal and a second local clock signal dependent upon the first local clock signal. In another embodiment, the gating logic produces the intermediate clock signal dependent upon the global clock and gating signals and a feedback signal. The output section produces the feedback signal and one or more local clock signals.

摘要： The circuit library available for logic synthesis is limited to a single dynamic circuit block or logic synthesis block. The circuit design method includes first defining the logic synthesis block and then performing logic synthesis for a predetermined logical operation to be implemented. The logic synthesis step constrained to the single logic synthesis block produces an intermediate circuit design which necessarily comprises a series of dynamic circuit blocks, each associated with a single reset signal. Once the intermediate circuit is produced, the circuit design method includes eliminating unnecessary devices from the intermediate circuit to produce a final logic circuit, and then sizing the devices in the final circuit to complete the design.

摘要： An apparatus, a method and a computer program product are provided for conserving energy during functional mode of a processor by disabling the scan chain. By inserting logic gating into the scan chain it is possible to disable the scan chain during the processor's functional mode. During functional mode the scan out port of the latch bit in a scan chain toggles, which leads to unnecessary energy consumption. By gating scan control signals and the scan out port of a latch bit, the scan chain segment between latch bits can be disconnected. Therefore, the scan control signals can disable the scan chain during functional mode.

摘要： A latching dynamic logic structure is disclosed including a static logic interface, a dynamic logic gate, and a static latch. The static logic interface receives a data signal, a select signal, and a clock signal, and produces a first intermediate signal such that when the select signal is active, the first intermediate signal is dependent upon the data signal for a period of time following a clock signal transition. The dynamic logic gate discharges a dynamic node following the clock signal transition dependent upon the first intermediate signal. The static latch produces an output signal assuming one of two logic levels following the clock signal transition, and assuming the other logic level in the event the dynamic node is discharged. A scan-testing-enabled version of the latching dynamic logic structure is described, as is an integrated circuit including the latching dynamic logic structure.
