Patent ID: 8892967

Claim:
A measurement device comprising: a group of logic blocks, which includes at least one combination of a logic block having at least one logic device, a sequential circuit for receiving, as an input, an output of the logic block, a bypass for bypassing the logic block, and a switch for switching between a path inputting to the logic block and the bypass; and a control part, which: obtains a first count of errors in the group of logic blocks and sequential circuits under irradiation of high-energy particles when the switch is turned to the path through the group of logic blocks; obtains a second count of errors in the sequential circuits only under irradiation of high-energy particles when the switch is turned to the bypass in parallel with the path through the group of logic blocks; and subtracts the second count of errors from the first count of errors, to calculate an error rate of the logic block and sequential circuits separately based on a count of errors obtained by the subtraction.
