Recursive generation of uvm reg models using ralfgen

Hi,

When using ralfgen to generate uvm register models, the whole model is generated in one big file, include all the submodules.

This affect the reusability. I would prefer to reuse model that were generated for submodules instead.

As an example, here is a basic hierachical structure of a system:

Module A

 |-Module x

with their corresponding ralf file:

ModuleA_regmodel.ralf:

source Modulex.ralf

system ModuleA_regmodel {
  bytes 4

  block  Modulex = my_modulex@0X000000
}

Modulex_regmodel.ralf:

block Modulex_regmodel{
    bytes 4
    register dummy  {
        bytes 4;
    }
}

Running ralfgen will give me the following uvm regmodel in moduleA_regmodel.sv

`ifndef RAL_MODULEA_REGMODEL
`define RAL_MODULEA_REGMODEL

import uvm_pkg::*;

class ral_reg_modulex_regmodel_dummy extends uvm_reg;
[...]
endclass : ral_reg_modulex_regmodel_dummy


class ral_block_modulex_regmodel extends uvm_reg_block;
[...]
endclass : ral_block_modulex_regmodel


class ral_sys_modulea_regmodel extends uvm_reg_block;
[...]
endclass : ral_sys_modulea_regmodel

`endif

Now, for reusability, it would be preferrable to have two files instead:

modulex_regmodel.sv

`ifndef RAL_MODULEA_REGMODEL
`define RAL_MODULEA_REGMODEL

import uvm_pkg::*;

class ral_reg_modulex_regmodel_dummy extends uvm_reg;
[...]
endclass : ral_reg_modulex_regmodel_dummy

class ral_block_modulex_regmodel extends uvm_reg_block;
[...]
endclass : ral_block_modulex_regmodel

`endif

moduleA_regmodel.sv

`ifndef RAL_MODULEA_REGMODEL
`define RAL_MODULEA_REGMODEL

import uvm_pkg::*;

class ral_sys_modulea_regmodel extends uvm_reg_block;
   rand ral_block_modulex_regmodel my_modulex;

[...]
endclass : ral_sys_modulea_regmodel

`endif

Now, is there a way to generate moduleA_regmodel as is, without deleting the modulex_regmodel class declaration after each generation?

I was thinking of having a modulex_regmodel_empty.ralf:

block Modulex_regmodel{
}

And source it in ModuleA_regmodel.ralf, but I get an error.

Other ideas?

Thank you!
