Timing Command Dictionary | SET END_MEASURE_CYCLE TIME |
|
|
∙The period of all scan test procedures equals the end_measure_cycle time or is the end_measure_cycle time multiplied by the number of cycles in the procedure.
∙The end_measure_cycle time is greater than the strobe time and less than or equal to the test cycle period.
∙No input pin forces occur after the end_measure_cycle time.
∙For each scan test procedure, each clock pin force event corresponds to the pair of force times in the timing file.
∙For each scan test procedure, each force event on a
∙The measure_sco time in the shift procedure, which defines the scan output measure time, is zero.
In some tester formats (such as UTIC), you can specify a separate timing definition for the shift procedure. In this case, the timing rules checker does not consider the shift procedure for compliance with the constraints listed earlier.
Arguments
∙integer
An integer time value specifying the final test cycle length. This number must match the period of the shift procedure.
Examples
The following example specifies a timing definition that satisfies all the constraints described previously.
//FlexTest Application Commands set test cycle 2;
setup pin costraints NR 1 0;
add pin constraints SR0 clk_a 1 1 1; setup pin strobes 2;
//FlexTest Timing File SET TIME SCALE 1 ns;
