Mentor v8.6_4 manual FlexTest application commands add clocks 0 clk

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).
