Timing Command Dictionary

SET SPLIT_BIDI_CYCLE TIME

 

 

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 test cycle. This number must match the period of the shift procedure.

Examples

The following example shows a timing definition satisfying all the conditions specified in the command description. Note that the shift clock timing and the capture clock timing are compatible. Also, note that the split_bidi_cycle time is greater than the force time and less than the bidi_force time in the first timeframe (0 < 500 < 550).

//FlexTest application commands set test cycle 2;

setup pin constraints NR 1 0;

add pin constraints clk_a SR0 1 1 1; setup pin strobes 1;

//FlexTest Timing file SET TIME SCALE 1 ns;

SET SPLIT_BIDI_CYCLE TIME 500; //matches shift period SET FORCE TIME 800 900;

SET BIDI_FORCE TIME 550 825; SET MEASURE TIME 700 850; SET CYCLE TIME 1000;

SET PROCEDURE FILE “g1” “design.g1”;

//Test procedure file for FlexTest

PROC SHIFT =

FORCE_SCI0;
