This dialog accumulates frequency testing results as the test or tests are performed. Each test that has been selected to run is placed in the left hand list when testing begins for that particular test. During each test, frequencies are appended to the middle list and a tick or cross is placed next to the frequency to indicate success or failure. If a test at a particular frequency failed, a comment is displayed next to the frequency showing which step of the test the failure occurred. If one or more of the frequencies for a test have failed then the frequency can be selected and a list of failure locations appears in the right hand list. Clicking on a failure location will make the Design Canvas jump to the particular component instance that recorded the failure. A failure location is a component instance whose flip flops are preceded by combinational logic that did not have time to settle at the tested frequency. Each individual bit of the component is displayed and the expected value compared to the actual value are shown. To clarify how each of the three lists are related. The 'Failure Locations' list contents is dependent on the frequency selected in the middle list, whose contents in turn is dependent on the particular test selected in the left hand list. Therefore to browse test results each test should be selected in turn to search for failures. |
