Abstract:
A simulator for simulating a digital circuit, comprising:an input circuit for inputting a plurality of test patterns to describe the characteristics of the digital circuit and for inputting a plurality of input signals to test the operation of digital circuit and a plurality of output signals to describe the expected output of the digital circuit based on the plurality of input signals; an applying circuit to apply the input signals to test the operation of the digital circuit to said test patterns to describe the characteristics of the digital circuit to form a simulated output signal to indicate a response based on said test patterns; a comparator circuit to compare said simulated output signal with the output signals to describe the expected output of the digital circuit based on the plurality of input signals to determine a difference between the simulated output signal and said output signals, wherein the operation of the simulation is stopped if said difference is greater than a threshold difference.
