Abstract: Apparatus for testing integrated circuits containing a controller or other sequential circuit at actual operating speed while minimizing the length of the test sequence and achieving high fault coverage are provided. The states of a state register are assumed controllable and observable, and a set of test patterns is obtained for a combinational circuit not containing said state register. An invalid-state generation logic circuit is added for generating invalid states, which are states contained in the generated test patterns but cannot be set by a normal transition from the reset state. A multiplexer is added for selecting the output of a next-state generation logic circuit or the invalid-state generation logic circuit for input to the state register based on a state transition mode selection signal. Signals corresponding to pseudo-primary outputs during test generation are made observable, and the multiplexer output signal is externally detectable as a state output signal.

Abstract: The invention provides a method of design for testability at RTL which can guarantee high fault coverage and a method of test sequence generation for easily generating test sequences for an RTL circuit which is designed to be easily testable by the method of design for testability. In the RTL circuit, scannable registers are selected so that the RTL circuit can attain an easily testable circuit structure such as an acyclic structure. This RTL circuit is timeframe expanded on the basis of a predetermined evaluation function and logically synthesized, so as to generate a timeframe expanded combinational circuit, that is, a gate level timeframe expanded circuit, as a circuit for test sequence generation.
