ALTLVDS_RX and ModelSim

I have the most basic LVDS receiver with PLL in my design both using Megafunctions. It compiles fine but when I try to simulate with ModelSim it gives me following error:

"Error: (vsim-3033) C:/CMOS_Sensor/DS/LVDS_receiver/lvds_receive.v(90): Instantiation of 'altlvds_rx' failed. The design unit was not found."

I have had this issue before with cyclone_iv_diffio module but adding the library to the path solved the issue but in this case I have tried to add the library which points to altlvds_rx module but Modelsim doesn't load it.

Any help is appreciated,

Thanks,

Drew

    Can you try with other QII version ie 13.1 to see if similar observation?

    By the way, did you check in the Megawizard if there is any other library required to simulate the altlvds_rx?
