    摘要: An exemplary embodiment of the present invention is a method for performing AC self-test on an integrated circuit that includes a system clock for use during normal operation. The method comprises applying a long data capture pulse to a first test register in response to said system clock. An at speed data launch pulse is applied to the first test register in response to said system clock. The data from the first register is input to a logic path in response to applying the at speed data launch pulse to the first test register. An at speed data capture pulse is applied to a second test register in response to the system clock. The output from the logic path is input to the second test register in response to applying the at speed data capture pulse to the second test register. A long data launch pulse is applied to the second test register in response to the system clock. An additional embodiment includes a system for performing AC self-test on an integrated circuit that includes a system clock.

    摘要: Method, system and program product are provided for reducing size of memory required for a switching node's forwarding table by employing forwarding tables of different types to map received data packets addressed to downstream nodes and upstream nodes to appropriate output ports of the switching node. The method includes receiving a data packet at a data transfer node of a network and selecting a forwarding table from multiple types of forwarding tables accessible by the node based on an attribute associated with the received data packet, and mapping the data packet to an output port of the node utilizing the forwarding table selected from the multiple types of forwarding tables based on the attribute associated with the packet.

    摘要: A method of controlling test data with a boundary latch module having a plurality of latches to facilitate logic built-in self-testing of an integrated circuit (IC) is provided which includes providing a plurality of selection devices for selecting initialization data to store in the plurality of latches of the IC's boundary latch module. The initialization data is selected from a plurality of scan paths of the integrated circuit, and the initialization data from at least one of the latches is provided as input to a logic circuit of the IC or output of the IC. In another aspect, the method includes selecting a datum from an external input or test-pattern generator of the integrated circuit for capture in at least one of the latches and input to a multiple-input signature register, which stores a signature of the integrated circuit resulting from the logic built-in self-testing.

    摘要: Method, system and program product are provided for packet flow control for a switching node of a data transfer network. The method includes actively managing space allocations in a central queue of a switching node allotted to the ports of the switching node based on the amount of unused space currently available in the central queue. In a further aspect, the method includes separately tracking unallocated space and vacated allocated space, which had been used to buffer packets received by the ports but were vacated since a previous management update due to a packet being removed from the central queue. Each port is offered vacated space that is currently allocated to that port and a quantity of the currently unallocated space in the central queue to distribute to one or more virtual lanes of the port.

    摘要: A technique is provided for simultaneous and/or selective self-testing of internal logic and asynchronous boundaries of an IC having a plurality of clock domains. A clock command is generated by an on product clock generator for each clock domain simultaneously; and an asynchronous receive clock driver provides a programmable delay to a capture clock based on predetermined cycle requirements of the asynchronous boundaries. Asynchronous boundary test requirements are defined exclusively from the perspective of the asynchronous boundary receiver latches, thereby reducing dependencies among clock domains. Advantageously, the design of internal logic and asynchronous boundaries of each clock domain, ultimately residing within an IC, can proceed without a priori knowledge of how the clock domain will eventually be used in aggregation with other clock domains.
