- the present invention relates to a test apparatus and a test method for testing a device under test.
- a test apparatus for testing a device under test such as a semiconductor supplies a test signal having a predetermined test pattern to the device under test, and detects a value of a signal output from the device under test according to the test signal. Then, the test apparatus determines the quality of the device under test by comparing the detected signal value with the expected value.
- Such a test apparatus includes a pattern generator.
- the pattern generator sequentially executes each test instruction included in the test instruction sequence (sequence data).
