Abstract
A test apparatus that tests a device under test, including a control apparatus that controls testing of the device under test, a test unit that sends and receives signals to and from the device under test, and a buffer section that buffers access requests transmitted from the control apparatus to the test unit and, prior to completion of a write request to a predetermined buffer control address from the control apparatus, issues previously buffered access requests to the test unit side.
Claims8
A test apparatus that tests a device under test, comprising:
- a control apparatus that controls testing of the device under test;
- a test unit that sends and receives signals to and from the device under test;
- and
- a buffer section that buffers access requests transmitted from the control apparatus to the test unit and, prior to completion of a write request to a predetermined buffer control address from the control apparatus, issues previously buffered access requests to the test unit side, wherein
- in response to receiving the write request to the buffer control address, the buffer section does not buffer new access requests until issuance of the previously buffered access requests to the test unit side is finished.
A test method for testing a device under test performed by a test apparatus, wherein the test apparatus includes:
- a control apparatus that controls testing of the device under test;
- and
- a test unit that sends and receives signals to and from the device under test, the test method comprising:
- buffering access requests transmitted from the control apparatus to the test unit and, prior to completion of a write request to a predetermined buffer control address from the control apparatus, issuing previously buffered access requests to the test unit side, wherein
- in response to reception of the write request to the buffer control address, new access requests are not buffered until issuance of the previously buffered access requests to the test unit side is finished.
