发明名称 Apparatus for testing semiconductor integrated circuits
摘要 An apparatus for testing a semiconductor integrated circuit using an actual operating frequency of the semiconductor integrated circuit includes a test target circuit which is to be tested and has a scan path in the test target circuit for executing a test. The apparatus also includes a test pattern generation circuit which generates, after completion of the test, a signal for scanning out a test result synchronously with an edge of a test clock signal with a lower frequency than the actual operating frequency, and outputs a scan-out control signal to the scan path.
