Description

technical field

[0001] The invention relates to the technical field of performance testing of main control equipment in the nuclear power industry, in particular to the technical field of black-box testing of algorithm blocks of main control equipment, and more specifically, to a method and device for testing timing algorithm blocks based on MPU operation. Background technique

[0002] Safety issues are very important in the field of nuclear power, and it is especially clear in the software testing of timing algorithm blocks. For timing algorithm block testing, the testing methods generally include white-box testing and black-box testing. In white-box testing, it is necessary to Covering each branch path of the sequence algorithm block code needs to reach MC / DC (modification condition / decision coverage) coverage of 100%. In the black box test, it is necessary to confirm the value of each cycle of the timing algorithm block to ensure the correctness of the algorithm operation...
