Mentor v8.6_4 manual SET Endmeasurecycle Time

Timing Command Dictionary SET END_MEASURE_CYCLE TIME

Note that the measure_sco event for the first shift procedure cycle occurs at the end of the load_unload procedure. All other measure_sco events for shift cycles occur at the end of the previous shift cycles.

Unlike the SET SPLIT_MEASURE_CYCLE TIME command, this command ensures that all test cycles have measure events at the end--without splitting the original test cycle in two. Note that you can specify only one of the following commands in a timing file:

∙SET SINGLE_CYCLE TIME

∙SET SPLIT_BIDI_CYCLE TIME

∙SET END_MEASURE_CYCLE TIME

∙SET SPLIT_MEASURE_CYCLE TIME

If you place the SET END_MEASURE_CYCLE TIME command in the timing file, the timing rules checker ensures compliance to the following conditions:

∙The timeplate period equals the end_measure_cycle time that you specify with the SET END_MEASURE_CYCLE TIME.

∙The period of all scan test procedures either equals the end_measure_cycle time or is the end_measure_cycle time multiplied by the number of test cycles in the test procedure.

∙The end_measure_cycle time is greater than the measure_po time and equal to the period of the super timeplate.

∙The timing in each timeplate corresponds to the timing in the super timeplate.

∙The end_measure_cycle command is only valid for test patterns that do not have a capture clock or that use clock sequential patterns.

∙Each test procedure force event time for a clock pin corresponds to the capture clock timing in the super timeplate.
