METHOD FOR CHECKING POWER-OFF FUNCTION OF DESIGNED CIRCUIT

摘要

PURPOSE: A method for checking a power-off function of a designed circuit is provided to reduce a period for designing a circuit by verifying an operating state of a power-off block. CONSTITUTION: A control signal, a control gate, and information of a power supply block are set up(S10). An operating state of a power-off block is determined by checking a state of the control gate when a path tracking control signal is applied to a control gate according to the control signal(S30-S50). A path tracking operation, an operation for inverting the control signal, and an error decision process are respectively performed according to a buffer, an inverter, a logic element when the path tracking control signal is applied to the remaining circuits except for the control gate(S80,S90). An error output is reported if the state of error is decided(S110).
