Setting Test Speed

The Script Automation Test Tool application Speed

setting allows you to select the speed at which to run the test.

This setting applies only to the 5GT/s capable PETracer Summit, Summit T2-16, and Summit Z2-16 platforms. For

these platforms, the TrainerScripts folder has a Speed subfolder, which contains three generator scripts with names

related to the three speed settings:

o speed_2_5.peg: This empty script does not contain any instructions.

o speed_5_0.peg: This script contains a speed switch to 5 GT/s and a wait for 100 milliseconds.

o speed_auto.peg: This empty script does not contain any instructions.

When you select a speed setting in the application, the application copies the script corresponding to the selected

speed to the Speed subfolder and gives it the name switch_speed.peg. This file name is included at the end of the

common linkup script, so all Link/Transaction tests can use it. You can include this file name in any user-defined

test in order to use the Speed setting.

When you select a speed setting in the application, the application also modifies the following parameters in the

Recording Options and Generation Options for each test, before executing the test:

o If Speed = 2.5 GT/s, Recording Options Speed is set to 2.5 GT/s, and Generation Options TS Data Rate is

set to 2.5 GT/s.

o If Speed = 5.0 GT/s, Recording Options Speed is set to 5.0 GT/s, and Generation Options TS Data Rate is

set to 5.0 and 2.5 GT/s.

o If Speed = Auto, Recording Options Speed is set to Auto, and Generation Options TS Data Rate is set to

5.0 and 2.5 GT/s.
