when I tried to run the tcl proc from list.tcl in system console terminal, it shows I am missing parameter_inc.tcl and I can not find it in the test directory.
Yes, the parameter_inc.tcl file is not available as i can see from my site as well. This is not required to run the ethernet test.
The TCL that you suppose to run is main.tcl.
I understand you concern, the example design package come with all available scripts that sufficient to run the Ethernet test . I afraid that other script may not be available.
