Mentor v8.6_4 manual SET Splitmeasurecycle Time

SET SPLIT_MEASURE_CYCLE TIME Timing Command Dictionary

This command can also cause the application to split the non-scan test cycle into two tester cycles. The application splits the test cycle only if the measure_po event does not already occur as the last event of the test cycle.

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

∙The timeplate period is twice that of the split_measure_cycle time (unless the timeplate begins with init_force_pi, in which case the timeplate period is four times that of the split_measure_cycle time).

∙The period of all scan test procedures equals the split_measure_cycle time multiplied by the number of test cycles in the test procedure.

∙The split_measure_cycle time is greater than the measure_po time and less than the capture_clock_on time in the super timeplate.

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

∙For clock pins, each test procedure force event time corresponds to the capture clock timing in the super timeplate. Note that the tool subtracts the split_measure_cycle time from the capture_clock times before this check.

∙Each test procedure force event on a non-clock pin corresponds to the force_pi time in the super timeplate.

∙The measure_sco time in the shift procedure, which defines when the scan output measure should occur, is zero.

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
