Tripple Speed Ethernet Simulation Error :[vlog-2110] Illegal reference to

Hi guys

I want to simulate the altera TSE IP core to understand control register read write and working of the core. I have followed the method described in ug_ethernet (https://www.altera.com/content/dam/a...g_ethernet.pdf) section 9-4 & 9-5.

But unfortunately I am getting these errors


# vlog -reportprogress 300 -sv /home/vinod/edatools/camera_prj/tse/simulation/submodules/mentor/altera_tse_ph_calculator.sv -work i_tse_mac

I checked the altera_tse_ph_calculator.sv file also but that is encrypted.
I am a newbie to Modelsim and don't know scripting and libraries compilation.

FYI
>> I have installed "Quartus Prime Version 15.1.0 Build 185 10/21/2015 SJ Lite Edition " in Ubuntu 12.04 LTS.
>> I am developing a UDP packet transmitter using Altera TSE IP core. I have generated the Tripple Speed Ethernet MAC IP core using Qsys and I'm instantiating the "tse.v" top module in my design.
>> To do proper initial configuration of the TSE MAC IP core I need to read and write its control registers, so for that also I have written all the needed code.
Now before putting my design on the FPGA I wanted to test it by Simulating via Altera Native Simulation.

Any help would be greatly appreciated.
Thank you.
