Timing Command Dictionary SET END_MEASURE_CYCLE TIME
FastScan and FlexTest Reference Manual, V8.6_4
A-39
• 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 non-clock pin
corresponds to the force time in the timing file.
• 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;
