Modelsim Error: (vcom-11) Could not find altera.maxplus2

Altera_Forum · ‎11-04-2014

Hello all,

I am completely new to vhdl, altera and modelsim so please bear with me if the question is too simple. I have tried to scout the web for any leads - but so far without any real progress.

I have created a simple structural design based on 74xxx components from the altera maxplus2 library (altera\13.0\quartus\libraries\vhdl\altera). I know this can be done as behavioral - but I am transferring an old TTL design that I want to verify.

I have included in my vhdl file:

LIBRARY altera;

USE altera.maxplus2.ALL;

Following setp by step the "getting started wtih quartus ii simulation using the modelsim-altera software" guide to open up modelsim with nativelink I get the following error message in the transcript window:

# ** Error: (vcom-11) Could not find altera.maxplus2.

And from this point I cannot progress. I have tried to compile the maxplus2 library with the modelsim compile functionality - but in all honesty I am not really sure what I am doing. I get a maxplus2 folder in RTL-WORK directory - but it doesnt help at all as I get the same error when I re-execute the "do"-command line.

Any pointers as to where I can look for further reading on this topic or any advice to resolve this is highly appreciated.

All,

I found a potential solution over at xlinx's forum: http://www.xilinx.com/itp/xilinx10/isehelp/pp_p_process_compile_hdl_simulation_libraries.htm

From that discussion I used the following command:

vcom -93 -explicit -reportprogress 300 -work altera {C:\altera\13.0\work\maxplus2.vhd}

It appears that quartus' maxplus2 library gets compiled into the existing modelsim altera library.

Following this i could re-compile my "design" without any issues and get into simulation window.

Not sure whether this is the "appropriate" and long term solution - and not sure if it works as i have not completed my simulation yet - i have quite a few "vsim-3473 component not bound" errors to resolve first :-)

Please let me know if you have any other thoughts.
