Setting Test Speed
The Script Automation Test Tool application
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.
