libraries and packages

The background: I need to define my own type that I would like to use in entity's port. It looks like there is no other way to make this type public other than define it in package.

The code is

-- mvb_lib.vhd --

package mvb_lib is

type bit_cell is ('0','1',nl,nh);

end mvb_lib

If in my top object i declare

library mvb_lib

use mvb_lib.all

the compiler does not comply but when I use bit_cell it terminates with error object "bit_cell" used but not declared.

I found out, that I can use

use work.mvb_lib.all

in my file and in the properties of the file fill in "mvb_lib" into the library entry.

But this is a little bit strange for me. Is there other "clean" way of using packages in projects?

    Hi,

    The first notes you mentioned should work i.e

    -- mvb_lib.vhd --

    package mvb_lib is

    type bit_cell is ('0','1',NL,NH);

    end mvb_lib

    If in my top object i declare

    library mvb_lib

    use mvb_lib.all

    Did you make sure that you compiled the Package first before referencing it?

    Did you mean to have this file in the file list before other vhd files that use the library? Or do I need to make new project just to compile the library?

    Hi,

    you must have the files in the list before you can reference them. If you are still having problems, then send me the files of relevance and I will make a script for you and make the necessary changes.

    Thanks

    I am sending you back a zip file called mvb_lib_project.zip.

    Extract this file and run the script "compile.do" in the

    Tools-> TCL-> Run Macro option in Modelsim.

    you will see that there are two unbound components

    data_pe : entity work.edp

    port map (

    a => data_in,

    q => data_r,

    clr => reset,

    clk => clk

    );

    -------------------------------------------------------------------------------

    -- Positive edge detector for data_in

    -------------------------------------------------------------------------------

    data_ne : entity work.edn

    port map (

    a => data_in,

    q => data_f,

    clr => reset,

    clk => clk

    );

    but this is because you have not provided me the edn and edp files.

    If you add this to the compile.do script but BEFORE the top level file, your project will compile.

    Hope this helps

    Thanx!

    In my Quartus II 7.2 I found only menu item Tools/TclScripts which opens window with a list of 2 tcl scripts that are in /quartus/common/tcl/apps/gui directory. There is no button nor input field where I can input the script you send me.

    Do I require also the other files beside the compile.do, which are in the directories or are these files generated by the compiler?

    Hi,

    Sorry for the delay in my reply.

    I was under the impression you were just using modelsim and not Quartus.

    Anyway I have rebuilt your files, re-naming them and giving the design more structure, so it is cleaner.

    the following zip file allows you to

    1) Compile the design in Modelsim

    2) Compile the design in Quartus II

    When you extract the zip file it will be evident on how to compile in either one of the tools

    Hope this helps
