    摘要: Disclosed herein is an improved logic module used for logic emulation along with an enhanced logic emulation board subject to logic verification. The logic module has a plurality of programmable LSIs capable of programming logic and a plurality of switching LSIs capable of programming connections, the LSIs being mounted on one or both sides of a board. Peripheral portions of the board carry connectors for electrical connection to the outside. There are two types of data lines: those directly coupling the connectors to the programmable LSIs, and those linking the connectors to the programmable LSIs via the switching LSIs. The programmable and switching LSIs constitute a crossbar connection arrangement. The logic emulation board has connectors for connection to a logic emulation module, and lands for supporting LSIs targeted for development. Pins of the connectors and the lands are interconnected on a one-to-one basis. Also disclosed here is an upgraded module structure permitting a multiple-stage module setup together with an advanced cooling structure for modules.

    摘要: A signal transmitting circuit includes a circuit block having a driving circuit and an intra-block transmission line for transmitting a signal from the driving circuit, a circuit block having a receiving circuit and an intra-block transmission line for transmitting the signal to said receiving circuit, and a main interblock transmission line for propagating a signal between the driving and receiving circuit blocks. The inter-block transmission line is terminated by a resistor having substantially the same impedance as the interblock transmission line. The intra-block transmission lines are provided with a resistance element having a resistance substantially equal to a value derived by subtracting half of an impedance of the inter-block transmission line from an impedance of the intra-block transmission line, to lower signal amplitude and suppress reflections of a signal at branch points along the main interblock transmission line, thereby enabling a high-speed signal transfer.

    摘要: A signal transmitting circuit includes one or more circuit blocks having a driving circuit and an intra-block transmission line for transmitting a signal produced by the driving circuit, one or more circuit blocks having a receiving circuit and an intra-block transmission line for transmitting the signal to said receiving circuit, and a main interblock transmission line for propagating a signal between both of the driving and receiving circuit blocks. Inter-block transmission line is terminated at one or two ends by one or two resistors having substantially the same impedance as the interblock transmission line itself. Each of the intra-block transmission line is provided with a resistance element having a resistance equal to or close to a value derived by subtracting a half of an impedance of the inter-block transmission line from an impedance of the intra-block transmission line, to lower signal amplitude and suppress reflections of a signal at branch points along the main interblock transmission line, thereby enabling a high-speed signal transfer.
