ABSTRACT:
In an apparatus for testing a counter circuit, a test pattern is used to drive the counter circuit to obtain an output pattern. The output pattern is compared with an expected pattern in synchronization with the test pattern, thereby determining whether or not the counter circuit is normal. A phase between the output pattern and the expected pattern is initially adjusted by the testing apparatus.
