Logic emulation module and logic emulation board

Abstract

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.
