Abstract
Provided herein are an error detection device and an error detection method to intuitively identify the reason for a handshake failure. An entire state transition flow including each state based on the communication standard and a state transition condition to be executed between states is displayed as a state transition setting screen, and an immediately preceding state in which the state transition fails and the failed state transition condition are highlighted on the state transition setting screen, when the handshake with the device under test ends.
Claims8
An error detection device that transmits a test signal of a known pattern to a device under test, in a state where the device under test is transitioned to a signal return state by handshake based on a communication standard of the device under test, and detects an error in input data that is returned and received from the device under test in response to the transmission of the test signal, the error detection device comprising:
- an operation display configured to display, as a state transition setting screen, an entire state transition flow including each state based on the communication standard and a state transition condition to be executed between states;
- and
- display controller configured to control the operation display so as to highlight an immediately preceding state in which a state transition fails and a failed state transition condition, on the state transition setting screen, when the handshake with the device under test ends.
An error detection method for transmitting a test signal of a known pattern to a device under test, in a state where the device under test is transitioned to a signal return state by handshake based on a communication standard of the device under test, and detecting an error in input data that is returned and received from the device under test in response to the transmission of the test signal, the error detection method comprising:
- a step of displaying, as a state transition setting screen, an entire state transition flow including each state based on the communication standard and a state transition condition to be executed between states;
- and
- a step of highlighting an immediately preceding state in which a state transition fails and a failed state transition condition, on the state transition setting screen, when the handshake with the device under test ends.
