7. Switching to Version 1.1
Script
The PCIe Link Training Suite v1.0 automatically inserted a pause at
the beginning of the link training sequence. You had to click "Manual
Trigger" to start link training. The PCIe Link Training Suite v1.1
requires to have this sequence step being defined in the script.
When you load a script generated with v1.0 into the new v1.1
software, link training will immediately start after downloaded to the
instrument. To get the old behavior back, you have to modify the old
script as follows:
• After "Blocks:", insert the following line:
initial_pause: Pad0();
• After "Sequence:", insert the following line:
00. initial_pause, manual;
Note that you don't have to apply these changes unless you want to
load an old script into the new version of the Link Training Suite.
Setting Files
The jitter mechanism changed from PCIe Link Training Sutie v1.0 to
v1.1. When you use v1.1 or later to load a settings-file (*.ltss) which
was saved with v1.0, the jitter settings can't be restored. Instead,
jitter will remain untouched.
Settings that weren't available in v1.0 also won't be restored when
loading a settings file generated with v1.0. Those settings will remain
unchanged when loading a settings file.
