Timing Command Dictionary SET BIDI_FORCE TIME

SET BIDI_FORCE TIMEScope: Sets timing information
Usage
SET BIDI_FORCE TIME time_value_list
Description
Sets bidirectional pin force time for each timeframe.
The SET FORCE TIME command lets you specify one set of force times for all
pins of the device under test. However, to prevent bus contention on bidirectional
pins, the force times for these pins must occur after applying the tri-state control
signal. You specify this special bidirectional pin force time with the SET
BIDI_FORCE TIME command. The bidirectional pin force time you specify must
occur prior to the measure time in the same timeframe.
Note that this timing file command is similar to the BIDI_FORCE_PI statement
that FastScan uses in its TIMEPLATE definition.
Arguments
•time_value_list
The set of time values indicating when bidirectional pin forces should occur.
The number of list values must equal the number of timeframes in the test
cycle, as specified by the Set Test Cycle application command description in
Chapter 2.
Examples
The following example shows the SET BIDI_FORCE TIME command used with
the SET FORCE TIME and SET MEASURE TIME commands. Assume the test
cycle contains four timeframes.
Assume the timing file contains the following timing commands:
SET FORCE TIME 0 20 40 70;
SET MEASURE TIME 15 38 65;
SET BIDI_FORCE TIME 10 30 60 100;
