PreBuild libraries not working properly for Altera-Modelsim

Hi,

I m using altera-modelsim for my project. Quartus has generated a functional simulation model file(.vo). I see most of the altera libraries prebuild and mapped to my project. But when I simulate using my testbench, it fails reporting

Error: (vsim-3033) /$$$$$$$$$$$$$/simulation/modelsim/$$$$$$$$$$_timestamp_051817_141152.vo(1564905): Instantiation of 'stratixv_io_ibuf' failed. The design unit was not found.

My understanding is that this library is precompiled as a part of the altera-modelsim, and is present in the library list in my project. What could be the reason why the simulation stopped. Any directions?.

Regards

Jeebu Jacob Thomas

    Just an additional information: I m using Modelsim from Quartus15 for simulation and the Quartus14 for generating the simulation file.

    Solved the problem. The design was in verilog, and the library support was available only for VHDL. Once I changed the netlist generation option from verilog to VHDL, the error issue got solved.

    Why is there no library support in Verilog for StratixV ?. Or is it available?.

    There is, but perhaps you have a mixed-language design. Are you using the starter edition of Modelsim-Altera? I think it only supports a design that is all of one language or the other.
