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
