simulating GPIO Lite IP in Intel Modelsim

Jump to solution

I am trying to simulate a DDR serial receiver data stream design using GPIO Lite differential transmitters in the simulation stimulus module and GPIO Lite differential receivers in the simulation receiver module.  The modules compile OK but when I run the simulation, I get a pack of errors that indicate that I am missing part of the fiftyfivenm libraries.  A couple of the error messages are included below;

** Error: (vsim-3033) C:/a_Nightowl/ZTest3_NIOS/syn/wds_clk_xmit/altera_gpio_lite.sv(690): Instantiation of 'fiftyfivenm_ddio_in' failed. The design unit was not found.

I have mapped the fiftyfivenm library into my project.  I am obviously missing some step or other item in my project setup.  Can anyone help me???

Hi, 

Are you using the Quartus Standard edition? If so, try to simulate using the NativeLink Feature in Quartus software. All the library preparation and run commands are generated automatically.
