Inspection system, inspection device, and inspection method

An inspection device comprising:

• a communication circuit configured to communicate with a device to be inspected having an arithmetic operation function;
• a constant sending module configured to send, to the device to be inspected, a constant to be used when an arithmetic operation is carried out by the device to be inspected in accordance with an arithmetic problem, the arithmetic problem being sequentially selected from among a plurality of arithmetic problems;
• an operation circuit configured to carry out the arithmetic operation of the arithmetic problem;
• and
• a determination module configured to receive, from the device to be inspected, a result of the arithmetic operation acquired by carrying out the arithmetic operation using the constant in accordance with the arithmetic problem, compare the result of the arithmetic operation received with a result acquired by causing the operation circuit to carry out the arithmetic operation based on the constant sent by the constant sending module, and determine whether the arithmetic function of the device to be inspected works properly or not based on a comparison result,
• wherein the arithmetic problem is selected based on a count value of a counter of the device to be inspected,
• wherein the constant includes a first constant and a second constant, and
• wherein the count value by a value increases or decreases corresponding to a value of the second constant.

An inspection method of an arithmetic operation function for inspecting a device to be inspected having an arithmetic operation function comprising:

• sending a constant to be used in an arithmetic operation to the device to be inspected;
• receiving, from the device to be inspected, a result acquired by carrying out an arithmetic operation in accordance with an arithmetic problem sequentially selected from among a plurality of arithmetic problems using the constant;
• carrying out an arithmetic operation of the arithmetic problem by an operation circuit based on the constant sent;
• comparing the result received from the device to be inspected with a result of the arithmetic operation of the operation circuit;
• and
• determining whether the arithmetic operation function of the device to be inspected works properly or not based on a comparison result
• wherein the arithmetic problem is selected based on a count value of a counter of the device to be inspected,
• wherein the constant includes a first constant and a second constant, and
• wherein the count value by a value increases or decreases corresponding to a value of the second constant.
