    摘要: A method for designing a circuit. The method includes (i) providing a netlist of a design and (ii) dividing the netlist into N user logics, N being a positive integer. After said dividing the netlist is performed, the N user logics in N macro test wrappers are instantiated resulting in N instantiated logics. After said instantiating the N user logics is performed, the N instantiated logics are processed. After said processing is performed, a result of said processing is back-annotated to the netlist.

    摘要: Additional circuitry is included in an input cell design structure for an integrated circuit to detect and report transitions on an input that was expected to be stable, and to store that event for later analysis. Two or more modified input cells may have their error indications daisy-chained together to minimize additional routing. The storage elements may be included in a scan chain to allow for isolation of which input had the unexpected transition.

    摘要: The present invention relates to a method, and a respective system, and computer program product for sending data packets along a predefined data path, wherein the receipt of a packet is acknowledged within a predefined time delay that was preset and tuned according to the duration of the send process via said data path. Packets that were sent along the data path are also entered into a pipeline. The pipeline is tuned to have a depth of a predetermined number of clock cycles that correlates to the predefined time delay for the receipt of an acknowledgement message. For a packet in the output registers of the pipeline it is checked if an acknowledge message for the packet was received. Otherwise the packet will be sent again. Especially, the pipeline can be used as a bus trace vehicle.

    摘要: The present invention relates to a method and system for transferring a stream of data from a first higher-speed subsystem of a computer to a plurality of lower speed subsystems, wherein the stream is structured in a sequence of blocks of different bit length, and a block is to be transferred to a specific one of said lower-speed subsystems. A corresponding method uses a queue for buffering the data, which includes control bits [c], [u], [k] to encode the further processing relevant for the association of the data block with a specific one of said lower-speed subsystems, when the queue entry is decoded at the output register of the queue.

    摘要: The invention provides a method of transmitting data via a bus system coupling a plurality of bus participants with an arbitration procedure for the plurality of bus participants. The invention further enables bus arbitration during a first transmission since that the bus can be granted for a second transmission following the first transmission without wasting bus cycles. This is accomplished by determining the number of cycles remaining for the first transmission according to memory boundary and transmission packet boundary conditions.

    摘要: A circuit for checking the memory array address and contents is described. The circuit consists of at least one write address counter (120) and at least one read address counter (130). Before a data word is read into the array, each of its check bits are XORed with one bit of the address location at which the word is to be written. On reading out the word, the check bits are again XORed with the bits of the address location to restore their original value and the parity of the data word is checked. If the parity is found to be incorrect then it is known that an error has occurred either on reading in or reading out and the appropriate action can be taken.
