Modularization of SystemVerilog

archive

Hi guys,

I have an question concerning modularization, but I have not found it in one of the following books: "Writing Testbenches using SystemVerilog" and "SystemVerilog for Verification". So, I hope you can help me.

I have written much classes, which are all in ONE file so far, but this is not the target state I wish for this project. The problem is, that for example, one class instantiates another class and I don't know, how to separate the classes.

Is a mechanism available, as C-Header-Files?

I hope you can help me, because several smaller files are much better than one singe huge file.

Thanks for your help!
If the answer should be in one of the itemized books, please sorry, I haven't found it!

Sebastian

  • Hi Sebastian,

    If you have a large number of classes to manage, I would suggest putting them in a SystemVerilog package (this works in a similar way to packages in VHDL).

    If you want to use a similar mechanism to C header files, you can always use the Verilog `include "filename" macro.

    e.g. in "pkg.sv"

    package pkg;

    `include "class1.sv"
    `include "class2.sv"
    ...

    endpackge

    To use package in module (usually in another file):

    module top;

    import pkg::*; //make all package items visible here

    ...

    endmodule


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

    Hope that helps.
    Regards,
    Dave
