Abstract:
A functional logic circuit verification device for verifying the operation of a functional logic circuit, by implementing a circuit that is functionally equivalent to the functional logic circuit and by supplying electric signals thereto, the device comprising:an equivalent logic circuit mounted on a circuit board and composed of programmable logic elements, the equivalent logic circuit implementing logic specifications, of only a part of the functional logic circuit, to a gate circuit diagram level of the part of the verified functional logic circuit; a functional equivalent board which implements a circuit that is functionally equivalent, for input and output, to an other part of the verified functional logic circuit; one or more functional equivalent board connectors for connecting the functional equivalent board to the circuit board on which the equivalent logic circuit is mounted; an input/output section for implementing input and output of the functional logic circuit verification device; and one or more input/output section connectors for connecting the input/output section to the circuit board on which the equivalent logic circuit is mounted.
