Looking for example testbench for Cyclone-V Transceiver Custom_PHY IP from UG-01080-1.7

Hi,

  I am looking into the Altera Transceiver PHY IP Core User Guide, UG-01080-1.7 (June 2012).   I followed section 7, “Custom PHY IP Core”  to generate a custom PHY core using the Quartus 23.1-based MegaWizard and IP Catalog for my Cyclone-V FPGA.  I have all Verilog files generated for the custom PHY IP in a new folder tst_xcvr_phy_custom.

Next, I tried to do a basic loopback simulation of this custom PHY core.  Page 7-28 in the user guide states :

............ However when I try the "Altera wiki" link I get

.... not sure why I get this, I do have an active Altera account.

 Perhaps this Altera-Wiki has been migrated to a Github Altera Transceivers (PHY IP)  examples repo ?   Can someone help me get an example testbench for the Cyclone-V custom PHY IP ? I have QuestaSim and ModelSim for simulating with it.
