compile intel libraries for modelsim stand alone


I am trying to simulate a synthesized netlist in modelsim standalone. The file is synthesized from infered memory and uses M20K rams. The file ​in addition to the ieee libraries declares:

library twentynm;

 use twentynm.twentynm_components.all;

library altera;

 use altera.altera_primitives_components.all;


I created both libraries and compiled eda/sim_lib/twentynm_components.vhd   and

eda/sim_lib/twentynm_atoms. vhd to twentynm.

and compiled

eda/sim_lib/altera_primitives.vhd   and

eda/sim_lib/altera_primitives_components.vhd  to altera.


upon further compiling I realized that som of those file required an additional library, altera_lnsim, which I created and comiled

eda/sim_lib/altera_lnsim_components.vhd  to it.


All libraries compiled successfully without errors or warnings and I can see the compiled design units in their respective libraries. Further more I can compile my DUT file in the project without errors.   BUT!!............


when I start the sim, while the design is loading I get warnings when the synthesized netlist tries to load complaing about :


Component instance "inst : generic_m20k" is not bound


Upon further inspection of one of the library files that I compiled,

eda/sim_lib/twentynm_atoms. vhd I that noticed that it contains a package at the top of the file and many entity/architect constructs too. And these constructs all have a use clause :


use work.twentynm_atom_pack.all;


In this is where the generic_m20k is instanced.



How can it be looking for twentynm_atom_pack in library work????


this is my issue. unless someone can point me to what I'm doing wrong.

To run the simulation, you have to add library model for that specific family device, ie twentynm library for your case. Find and include necessary precompiled libraries for modelsim in here /quartus/eda/sim_lib/ . My advice is to use nativelink flow to set up the simulation environment for your project. It has self-generated script and is more easier way than manually adding those libraries. Refer to link to understand its flow.

Thanks for the info. I had created and compiled all the libraries manually. Did not know about the native link flow. Anyway I did create all the libraries correctly but my issue turned out to be a missing –L altera_lnsim in my vsim command. Next time I’ll have the tools do the heavy lifting for me.
