Method for stimulating functional logic circuit with logical stimulus

A method is claimed for stimulating a functional circuit with logical stimulus, in order to determine the response of the functional circuit to that logical stimulus. The claimed method comprises the steps of (a) configuring a reconfigurable logic apparatus to implement the functional circuit, said reconfigurable logic apparatus comprising N reprogrammable logic devices, where N is a number greater than one, said N reprogrammable logic devices being interconnected by reprogrammable interconnect devices, and said functional circuit being implemented by at least two of said N reprogrammable logic devices; (b) converting the logical stimulus into input electrical signals; (c) inputting said electrical signals to said N reconfigurable logic apparatus which is configured with the functional circuit; and (d) receiving output electrical signals from said reconfigurable logic apparatus; and (e) converting said output electrical signals into software form. Also claimed are methods of simulating a functional circuit design, and a method of simulating digital logic networks.
