Abstract
A circuit verification method, including the following steps: inputting a circuit design data to a processor, wherein the circuit design data includes a plurality of logic circuits and a plurality of detection nodes, each logic circuit includes a control terminal and a plurality of input terminals, and is configured to output a signal to the detection node; inputting a plurality of first-stage property command to the processor to generate a plurality of first-stage formal commands, and the first-stage formal commands are configured to verify whether signals of the detection nodes remain stable when a signals of the control terminal of each of the logic circuits does not changed; finding a first part of the detection nodes by a formal method according to the first-stage formal commands; and finding a second part of the detection nodes by a formal method.
