摘要： In a verification supporting apparatus, a recording unit records a DIRW matrix in which a state transition possibly occurring in a register of a circuit to be verified and information concerning validity of a path corresponding to the state transition are set and an acquiring unit acquires a control data flow graph that includes a control flow graph having a data flow graph written therein. When a register is designated for verification, a data flow graph having described therein the designated register is extracted from the control data flow graph. From the data flow graph extracted, a path indicating the flow of data concerning the register is extracted. The state transition of the path extracted is identified and if the state transition is determined to be is set in the DIRW matrix, information concerning the validity set in the DIRW matrix and the path are correlated, and output.

摘要： A verification support apparatus that verifies operation of a circuit includes a receiving unit, a detecting unit, and a determining unit. The receiving unit receives implementation description data of the circuit. Based on the implementation description data, the detecting unit detects a functional block that is in the circuit and includes an external input terminal that receives an external input signal. Based on a detection result of the detecting unit, the determining unit determines the functional block to verify an abnormal-event operation. The abnormal-event operation is an operation that differs from an operation implementing a function of the circuit.
