Modelsim starting vsim with out typing the additional -L <library> each time

Hi,

 

I see other projects which start vsim without specifying the additional libraries it uses.

 

On my simulation projects, I have to use the -L option to start vsim otherwise modelsim will complain module 'X' is not defined.

 

For example, I manually compile quratus primitives quratus_mf.v from the eda library and name it altera_mf_ver.

 

To start simulation with vsim I have to use vsim -L altera_mf_ver work.top otherwise model sim will error out with. For example, the issue I have is that I need PLL megafunction but alt_pll not defined unless I include altera_mf_ver.

 

I check to see my library is in the [Library] section to my project setting file *.mpf which thought would help but for my project

I still have to add -L altera_mf_ver option in the vsim command each time. How does everyone else do it?

Hi,

 

Are you using the Intel FPGA Edition of ModelSim or a standalone edition? If using the Intel FPGA edition, the device libraries should already be precompiled for the simulator and you can see them in the libraries list.

 

If using a standalone version, you will need to compile the device libraries for the simulator via Quartus -> Tools- > FPGA Library compiler. Select the simulator , specify the path to the simulator and then choose the device family and compile. This will create the device specific libraries for ModelSim.

 

To simulate the designs, you will need to specify the libraries using the -L option. The other way around is to compile the required device libraries into your designs work folder and then simulate. This way the libraries and components are all available in the Work library and you need not specify the -L option.

 

Another option is to specify the libraries in the Modelsim.ini file that resides in your work library. Edit the file and add the following lines to it:

Hi,

 

Thanks for the info.  I use standalone modelsim, but I just compile the quartus/eda/sim_lib/ sources directly from modelsim. 

 

I suspect your right that the ini file will allow this because I have a testbench from somebody else and it allows starting vsim without having to type -L option and its in the [Library] section which mentor docs says will allow not having to type this in for commmon libraries, but when I cant seem to duplicate this in my own project.

 

I tried adding the altera_mf_ver library to modelsim.ini also the project.mpf file but I still have to type -L altera_mf_ver.   Is there a way to tell what libraries are default loaded and runtime?  This would help debug if its a modelsim.ini sytax read error or something else.
