Dynamic voltage adjusting method for vehicle gauge ASIL-D chip

The invention provides a dynamic voltage adjustment method for a vehicle-specification ASIL-D chip, and the method comprises the following steps: enabling the working frequency of each MONengine to be configured after the chip is powered on and started, and enabling the working frequency of each MONengine to be higher than the working frequency of a surrounding module; the RCORE is connected with each module for communication through the uart, sends a broadcast command and configures each MON engine to start operation, after the operation is completed, the result is sent to the CKengine through the uart, the CKengine verifies whether the calculation result of each MON engine is correct or not, and the DCDC is configured according to the verification result to reduce or increase the voltage. In the adjusting method, according to the principle that the carrier activity is improved after the chip is heated, the voltage can be properly reduced, and the circuit can work normally, compared with a traditional voltag
