Global Directive, `incude "features.vh"

Hi,

Thank you for taking time to read my post.

I am using Quartus PRO 18.1, with verilog HDL. I would like to understand how Quartus uses the declarative statements. I have a file, features.vh, which contains a list of directives that I use to include certain modules in my code. I would like to to declare these directives at the top module and have them also be declared for all other modules. I suppose my goal is to determine how to define global directives (if there is such a thing).

 

For example,

My top level module contains:

 

`include "features.vh"

 

and my features.vh contains:

 

`define USE_THIS

`define USE_THIS2

 

For my top level module, everything works as expected, however for other modules, the USE_THIS, and USE_THIS2 are not declared. If for all modules I include `include "features.vh" , then I can use  USE_THIS, and USE_THIS2 for those respective modules. Is there a way to declare the global directives?

 

Thank you for all of your help.

Hi,

As far as I know there isn't a way to have global directives. You'll have to add `include "features.vh" to all the modules using the features.vh header file.

Thank you for your reply.

It looks like having, `include "features.vh" at the top of each of my modules is one solution.

I also noticed that in Quartus > assignments > settings > Verilog HDL input and add MACRO =1 will add the following to the QSF:

 

set_global_assignment -name VERILOG_MACRO "MYMACRO=1"

 

which will allow directives to engage in all modules.
