摘要： A variable is allocated to a statement that designates an event associated with a function call in an assertion. Generation of the event at an arbitrary time on a continuous time series is detected, and a value corresponding to a meaning of the statement is assigned to the variable. Whether or not a condition corresponding to the meaning of the statement is satisfied is determined based on the value of the variable at each time on a discrete time series.

摘要： A design automaton extractor extracts a design automaton from design description data, and a property automaton extractor extracts a property automaton from property description data corresponding to the design description data. A matched state detector counts all states of the design automaton, detects matched states matching the property automaton from all the states of the design automaton, and counts the matched states. A coverage calculator obtains a ratio of the number of matched states to the number of all the states of the design automaton, thereby calculating a coverage representing the degree of correspondence of the property description data to the design description data.

摘要： According to one embodiment, an object retrieval apparatus includes a query acceptance unit and a collision decision unit. The query acceptance unit is configured to accept a retrieval query indicating (N−1)-dimensional surface in N-dimensional space (N is an integral number larger than or equal to three). The collision decision unit is configured to decide whether the (N−1)-dimensional surface intersects N-dimensional cuboid positioned in the N-dimensional space. The collision decision unit decides by using a plurality of decision functions. The plurality of decision functions includes zero-th˜(N−1)-th decision functions to decide whether at least a part of at least one of X-dimensional face (X is all integral numbers larger than or equal to zero, and smaller than or equal to (N−1)) of the N-dimensional cuboid is included in the (N−1)-dimensional surface.

摘要： A state-transition system includes a plurality of states and a first transition representing a state-change based on an external event occurred into a system to be checked. A plurality of requirement items includes a precondition and a postcondition in correspondence with the external event. By partially selecting the precondition and the postcondition from the plurality of requirement items, a state map to map a state onto truth values of the precondition and the postcondition is generated. By contracting the state-transition system with the state map, a quotient state-transition system is generated. The quotient state-transition system includes a plurality of second transitions among a plurality of groups each having states. By tracing each second transition in the quotient state-transition system, a representative transition path is generated. The representative transition path is regenerated as a transition path in the state-transition system. The transition path is output as a test case.
