ABSTRACT:
A hardware simulator comprises a plurality of interconnected programmable logic devices (20) which are connected via a data bus (22) and a control bus (24). Address signals on control bus (24) are read by an interconnect logic block (18) associated with each device to selectively link the output latches and input latches of the devices (20) to the data bus (22). Accordingly, a series of signal transfers is carried out between the devices simulating the hardware. The interconnect logic blocks may be programmed to provide whatever connections between devices are required.
