A testing device has plural pin electronics substrates and a control substrate. The control substrate includes a first instruction code memory storing an instruction code, a first program counter incrementing a count in synchronization with a clock, a code analysis circuit analyzing the instruction code read from the first instruction code memory in accordance with a counter value, and a control data output control circuit outputting control data for controlling the pin electronics substrates in accordance with the instruction code. Each pin electronics substrate includes a first pin memory storing pin data, a second program counter incrementing a count in synchronization with the clock, and a pin data output control circuit adjusting, based on control data, the count value of the second program counter and outputting pin data read from the first pin memory, the pin data being dependent on the count value of the second program counter. |
