In order to realize the design of a circuit that fully meets the requirements of the ARINC659 bus specification, it is necessary to design a verification method that can completely and fully verify the design requirements of the circuit. The traditional verification method for the circuit cannot solve the special requirements of the circuit verification. The high fault tolerance and high real-time characteristics of the ARINC659 bus fully verify the circuit, which is difficult to meet the requirements of design verification
