Rather than writing the PCIe core parameters down, you can convert the .qsys XML file to Tcl, and have "software" write the parameters down for you ...

You can use this script to generate a Tcl equivalent of your Qsys system, and then have that Tcl decide what parameters to include, eg., create a .qsys file for 14.0 or 13.x, taking care to only include parameters expected by that version of Quartus.

The fact that you can do this leads to the obvious question; Why did Altera use XML for .qsys files, when they could have just used Tcl?

Cheers,
