SET SPLIT_MEASURE_CYCLE TIME Timing Command Dictionary
• For clock pins, each test procedure force event time corresponds to the pair
of pin force times. Note that the tool subtracts the split_measure_cycle from
the force times before this check.
• Each test procedure force event on a non-clock pin corresponds to the force
time for all pins.
• 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
Arguments
• integer
The time value at which to split the non-scan cycle. This number must match
the shift procedure period.
Examples
The following FlexTest example shows a timing definition that satisfies all the
conditions specified in the command description. Note that the shift clock timing
is compatible with the capture clock timing. Also, note that the
split_measure_cycle time is greater than the measure time in the first timeframe
and less than the force time in the second timeframe (400 < 500 < 800).
