SET SINGLE_CYCLE TIME

Timing Command Dictionary

 

 

SET SPLIT_MEASURE_CYCLE TIME

Arguments

integer

Time value that specifies both the scan and non-scan cycle duration. This number must match the period of the shift procedure.

Examples

The following example satisfies all the timing constraints listed in the command description. Note that the shift clock timing and the capture clock timing are identical.

Assume you have entered the following FlexTest application commands:

//FlexTest commands set test cycle 2

setup pin constraints NR 1 0

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

The corresponding timing file contains the following commands:

//FlexTest timing file SET TIME SCALE 1 ns;

SET SINGLE_CYCLE TIME 1000; //matches shift period SET FORCE TIME 500 600;

SET MEASURE TIME 400 550; SET CYCLE 1000;

SET PROCEDURE FILE “g1” “design.g1”;

The design.g1 test procedure file contains the following shift procedure for scan group g1:

PROC SHIFT =

 

 

FORCE_SCI

 

0;

MEASURE_SCO

 

400;

FORCE clk_a

1

500;

FORCE clk_a

0

600;

PERIOD

 

1000;

END;
