Quartus II - Version 12--- Simulation- Problem doing Functional Simulation-- Help

Hello,

I am using 32 bit, Quartus II version 12 tool. I am generating a simple RAM using Megafunction wizard, I would like to simulate the same.

I tried linking Quartus II to modelsim, but I get an error message saying...

** Error: (vlog-7) Failed to open design unit file "c:/altera/12.0sp1/quartus/eda/sim_lib/mentor/altera_lnsim_for_vhdl.sv" in read mode.

is there any other way to simulate my design from quartus ii- version 12?. Please let me know. I have been stuck with this problem for more than a month now, and couldn't figure out a way.

Any help would be appreciated.

Thanks,

Manoj

    Does the model "altera_lnsim_for_vhdl.sv" exist in the directory? Do you setup the simulation using nativelink?

    Hi,

    Few things to check

    1. Have you configured your test bench?

    2. Have you ran compilation on your project?

    3. If the above two steps are done, did your simulator launch correctly?

    Thanks,

    Thanks for your reply. I tried native link, wasn't successful. So I switched over to Quartus 13.0 which comes with built in altera model sim, and altera libraries.

    Simulation works now.
