Is there any description about the structure of the INI file or example?

The INI file is a text file, similar to a Windows initialization file. 

You will need to include each type of function block and the resource block, the start up modes (target, normal, permitted), XD_SCALE range and unit code for example. This file is used by the test system to "re-initialize" the device under test to a known good state. 

There are also prompts for our automation tool kit. You can set the timers for how long the device needs to power up, power down, etc.
