    • A method for operating a plurality of data formatters, and a service and a device implemented by a computer are provided to enable all data formatters to format test results simultaneously with generation of the test results. Execution of a test processor is interrupted in a tester generating the test result of at least one DUT(Device Under Test) and interruption is informed to a user(102). While the test process is interrupted, the execution of the data formatters for formatting the test result is started by reading configuration data for identifying the data formatters to be started(104). If the data formatters are successfully started, interruption is released(106). Each step is started when the tester is executed and before the test process is executed. If the data formatters are not successfully started, the user is guided to override the interruption. If the user requests override, the interruption is released.

    • A semiconductor testing apparatus for surely detecting only opened edges that affect a test pattern and hence truly requires an error warning or the like. This semiconductor testing apparatus comprises real time selectors (40) and open detectors (50). The real time selectors (40) receive a plurality of waveform data outputted from a waveform memory (30) and a plurality of timing data outputted from a timing generator (20) and select and output predetermined waveform data and timing data. If an edge of the waveform data is followed by an edge of the same polarity with an interval therebetween that is shorter than a close-in limit time, then the real time selectors (40) open the following edge and output open signals. The open detectors (50) receive the waveform data, timing data and open signals outputted from the real time selectors (40) and output a fail signal if there exists an edge, which has the opposite polarity to the opened edge, within the close-in limit time preceding the foregoing opened edge.
