Instantiation of 'cyclonev_hmc' failed. The design unit was not found.

Hello , I am also facing the same kind of issue.

# Loading work.altera_mem_if_hard_memory_controller_top_cyclonev# ** Error: (vsim-3033) C:/altera/15.1/qts_ddr3/qts_ddr3/q_sys/synthesis/submodules/altera_mem_if_hard_memory_controller_top_cyclonev.sv(1387): Instantiation of 'cyclonev_hmc' failed.

I am working on an example design which I have downloaded from alterawiki.

It is getting compiled succeffully in quartus tool. But When I tried to simulate using altera-modelsim, it is throwing the above error.

kindly help me in solving the issue.

I am using quartus ii 15.1 and modelsim 10.4b

and also kindly let me know how to map the library files to modelsim for simulation.(At present , I am compiling all the design files and library manually)

Thanks alot
