Abstract
An ASIC based hardware accelerated simulation engine accelerates logic verification of integrated circuit designs utilizing a field of ASIC chips interconnected by direct connections. Communication between the chips has to be accomplished by switching technology internal to the chips. The switching technology employing programmable cross-point switches; i.e. hardware elements with input, output and command ports which propagate signals from the input ports to the output ports following a given permutation determined by values on the command port. The ASIC chip contains an instruction memory to program the logic elements thereof. A conveyor belt based implementation of the programmable cross-point switches provides reduced command bit requirements.
