SET SPLIT_BIDI_CYCLE TIME
Scope: Enables special timing rules checking
Usage
SET SPLIT_BIDI_CYCLE TIME integer
Description
Specifies the period for test procedures and splits the
Certain testers formats, such as UTIC and Compass Scan, do not allow state changes on both input pins and bidirectional pins in a single tester cycle. In this case, you must split each
If you place this command in the timing file, the timing rules checker ensures compliance to the following conditions:
∙The period of all pins is twice that of the split_bidi_cycle time.
∙The period of all scan test procedures equals the split_bidi_cycle time multiplied by the number of cycles in the test procedure.
∙The timing file contains the SET BIDI_FORCE TIME command to specify bidirectional pin force times.
∙All bidirectional pins have the same offset time.
∙The split_bidi_cycle time is greater than the force time and less than or equal to the bidirectional force time for each bidirectional pin.
∙For each scan test procedure, each force event time on a clock pin corresponds to the pair of force times specified in the timing file.
∙For each scan test procedure, each force event on a
