GTS PMA Example: Qsys Representation

Hi,

I am trying to understand the 1G PMA Direct Mode example design:

I would like to see the Qsys connections, however, it seems there is no .qsys file:

PS C:\altera_pro\TEST\intel_directphy_gts_1_example_design> Get-ChildItem -Path . -Recurse -Filter *.qsys     
PS C:\altera_pro\TEST\intel_directphy_gts_1_example_design>

Have I missed something?

Many thanks!
