Abstract
A logic block grouphaving at least one set including a logic block having at least one logic circuit and a sequential circuit that inputs the output of the logic block is arranged in an irradiation regionof a high-energy particle irradiation device, and subjected to irradiation with high-energy particles. A control sectioncalculates the error rate of the logic circuit from the value obtained by subtracting the number of errors of the sequential circuit when the logic block of the logic block groupis bypassed, from the number of errors of the sequential circuit and the logic block of the logic block group
