摘要： A signal delay cell for use in resolving hold time violations in an IC has a first multiplexer having a first functional data input node and a scan data input node TI and a second multiplexer having a second functional data input node, a second input node connected to the output of the first multiplexer and a flip-flop module. The propagation of a data input signal applied to the first multiplexer is delayed, and the hold margin of the flip-flop module is increased by transit through the first multiplexer. The signal delay cell is available to replace a flip-flop having a scan data hold problem, and also for use in solving a functional data violation in the same or another cell.

摘要： A scan flip-flop for generating an output signal based on a first input signal, a clock signal, a test input signal, a Launch On Shift (LOS) signal, a test enable signal, and a reset signal includes a logic circuit, a multiplexer and a flip-flop circuit. The logic circuit receives an inverted clock signal, the test enable signal, a intermediate test enable signal, and the LOS signal, and generates an intermediate output signal that is an inherent LOS scan enable signal. The multiplexer receives the test input signal and the intermediate output signal, and outputs the test input signal. The flip-flop circuit receives the test input signal as a second input signal, the clock signal, and the reset signal, and generates the output signal.

摘要： Spare gate cells for inclusion in an integrated circuit have multiple inputs and outputs and are capable of selectively performing, concurrently, multiple logic functions on signals appearing at the inputs. Selection of required logic functions depends on the connections of at least one of the inputs of the spare cell. One of the outputs is fed back to an input of the spare gate cell to provide certain functionality while other outputs are set to a fixed logical value. The spare gate cell may be configured to perform NOR, OR and inverter operations on inputs simultaneously.

摘要： A single power supply level shifter has first and second inverters in tandem that invert an input signal from a first voltage domain and provide a first inverted signal and an output signal in a second voltage domain. A charging control circuit charges a capacitor towards the second voltage when the input signal is high, and conducts a discharge current from the capacitor during a transition of the input signal from high to low to accelerate a corresponding transition of the first inverted signal from low to high. A third inverter controls a current reduction transistor in series with the first inverter, and a third control transistor connected between the input and the charging control circuit to accelerate the flow of discharge current during the transition of the input signal from high to low.

摘要： A single-supply digital voltage level shifter has a first inverter having a first input for receiving an input signal with a first voltage swing, and a first output for outputting a first output signal. A second inverter has a second input for receiving the first output signal, and a second output for outputting a second output signal with a second voltage swing, where the second output signal is a level-shifted version of the input signal. A comparison stage includes a first comparison stage input for receiving the input signal, a second comparison stage input for receiving the second output signal, and a comparison stage output for outputting a comparison stage output control signal. A control stage is connected in a circuit branch of the first inverter and has a control stage switch that assumes a non-conducting state dependent on a logical state of the comparison stage output control signal.
