    Abstract: Techniques for reducing scan overhead in a scannable flop tray are described herein. In one embodiment, a scan circuit for a flop tray comprises a tri-state circuit configured to invert an input data signal and output the inverted data signal to an input of a flip-flop of the flop tray in a normal mode, and to block the data signal from the input of the flip-flop in a scan mode. The scan circuit also comprises a pass gate configured to pass a scan signal to the input of the flip-flop in the scan mode, and to block the scan signal from the input of the flip-flop in the normal mode.

    Abstract: Techniques for clock gating a synchronizer are described herein. In one embodiment a circuit for clock gating a synchronizer comprises a clock-gating circuit configured to receive an input clock signal, and to selectively provide either the input clock signal or a fixed clock signal to the synchronizer. The circuit also comprises a comparator configured to compare a data value of a data signal input to the synchronizer, a first value of the synchronizer, and a second value of the synchronizer with one another, to instruct the clock-gating circuit to provide the input clock signal to the synchronizer if the data value, the first value, and the second value are not all the same, and to instruct the clock-gating circuit to provide the fixed clock signal to the synchronizer if the data value, the first value, and the second value are all the same.

    Abstract: A MOS device includes a first latch configured with one latch feedback F and configured to receive a latch input I and a latch clock C. The first latch is configured to output Q, where the output Q is a function of CF, IF, and IC, and the latch feedback F is a function of the output Q. The first latch may include a first set of transistors stacked in series in which the first set of transistors includes at least five transistors. The MOS device may further include a second latch coupled to the first latch. The second latch may be configured as a latch in a scan mode and as a pulse latch in a functional mode. The first latch may operate as a master latch and the second latch may operate as a slave latch during the scan mode.

    Abstract: A pulse generator includes a latch module for storing first/second states, a pulse clock module for generating a clock pulse, and a delay module for delaying the clock pulse at a second latch-module input. The latch module has a first latch-module input coupled to a clock, the second latch-module input, and a latch-module output. The pulse clock module has a first pulse-clock-module input coupled to the clock, a second pulse-clock-module input coupled to the latch-module output, and a pulse-clock-module output. The delay module is coupled between the latch-module output and second pulse-clock-module input or between the pulse-clock-module output and second latch-module input. The delay module provides functionally I1IA at a delay module output, where I1 is a function of I and IA is a function of IN0 and B0, and where I is a delay module input, B0 is a first input bit, and IN0 is a first net input.
