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

  • I think this is what you are looking for: package pkg; typedef class class_n; class class_1; class_n n; function new(); n = new(); endfunction endclass class class_n; endclass endpackage : pkg program test; import pkg::*; class_1 one; class_n n; initial begin one = new(); n = new(); end endprogram : test I also want to note that although the LRM states that you can put class definitions "outside of any of these", IUS only supports classes defined in program, module, or package. This should never be a problem since a package accomplishes the same thing but in a more reusable and structured format (see my previous post about using the import statement). Tim
