    摘要: A two-input multiplexer includes first, second, and third CMOS inverters, a transmission gate, and a tri-state inverter. The first CMOS inverter receives a select signal and outputs an inverted select signal. The second CMOS inverter receives a first input signal and outputs an inverted first input signal. The transmission gate receives the select signal, the inverted first input signal, and the inverted select signal, and outputs the inverted first input signal. The tri-state inverter receives the second input signal, the inverted select signal, and the select signal, and generates an inverted second input signal. The third CMOS inverter receives one of the inverted first and second input signals, and outputs one of the first and second input signals, respectively.

    摘要: A configurable delay cell for an integrated circuit includes a CMOS inverter and first through fourth transistors. A drain of the third transistor is connected to a drain of the fourth transistor for generating an output signal. A connection between an output terminal of the CMOS inverter and a source of the first transistor, a connection between the output terminal of the CMOS inverter and a drain of the second transistor, and a connection between the source of the first transistor and the drain of the second transistor are configurable, using an electronic design automation (EDA) tool, for achieving first, second, third, fourth, and fifth delay values. The resulting delay value can be programmed by making changes only in one or more of the metal layers of the integrated circuit.

    摘要: A configurable flip-flop circuit has modifiable connections between its circuit elements that allow it to be modified for primary and secondary uses. For example, the flip-flop circuit can be modified to provide secondary functions of NOR and NAND gates during an implementation of an ECO. At other times, the flip-flop circuit can be used to deliver normal flip-flop functionality. A configurable latch circuit is provided that can be modified to provide an output signal or an inverted output signal. A scan circuit is provided that can provide the functionality of a multiplexer.

    摘要: An integrated circuit (IC) design verification system includes a memory for storing an IC design and a processor in communication with the memory. The IC design includes multiple IP cores and the design verification apparatus includes multiple verification modules. The processor configures a first set of connections between the IP cores and the verification modules based on a first connection database and verifies each IP core independently using the first set of connections. Thereafter, the processor configures a second set of connections between the IP cores and the verification modules based on a second connection database generated based on the first connection database, and verifies the multiple IP cores together using the second set of connections.

    摘要: A method and controller for supporting out of order execution of instructions is described. A microprocessor is coupled to a coprocessor via a controller. Instructions are received by the microprocessor and the controller. Indices respectively associated with the instructions are generated by the microprocessor, and the instructions are popped from the first queue for execution by the coprocessor. The controller includes a first queue and a second queue. The instructions and the indices are queued in the first queue, and this first queuing includes steering the instructions and the indices associated therewith to respective first register locations while maintaining association between the instructions and the indices. The instructions may be popped off the first queue out of order with respect to an order in which the instructions are received into the first queue.
