Abstract
A method of testing input signals coupled to a circuit for performing a predetermined function is disclosed. The method comprises coupling input signals to inputs of the circuit by way of programmable interconnects; controlling the paths of the input signals within the circuit from the inputs to an output of the circuit; maintaining the states of the input signals coupled to the inputs of the circuit and routed to the output of the circuit; and testing output signals of the circuit to determine whether the correct input signals were provided to the inputs of the circuit by way of the programmable interconnects. A device having programmable logic which enables testing of input signals is also disclosed.
