Not able to find the package in the directory

susharma · April 15, 2015, 4:10am

Hello Team,

Please guide. How to import the package created in the project directory in the tb top file. I am importing in this way::

import spi_test_lib_pkg::*;

But it gives error

**** Error: C:\questasim_10.2c\examples\top_tb.sv(7): Could not find the package (spi_test_lib_pkg). Design read will continue, but expect a cascade of errors after this failure. Furthermore if you experience a vopt-7 error immediately before this error then please check the package names or the library search paths on the command line.**

Plus uvm_reg.svh and uvm_reg_map.svh are located at the following path:
C:\questasim_10.2c\verilog_src\uvm-1.1d\src\reg

These files are needed in the spi-apb environment.
I am trying to include these files but it gives more error. Please help me to clarify this.

I am learning SPI-APB verification using uvm-1.1d with Questasim-10.2c.

Thanks and Regards
Sunil Sharma

Try this:

// Similar to package example shown below
`include "spi_test_lib_pkg_file_includes.sv"

module tb;

   // All package imports
   import uvm_pkg::*;
   import spi_test_lib_pkg::*;
...
...

Example (uvm_pkg.sv) of how a package looks:

`ifndef UVM_PKG_SV
`define UVM_PKG_SV

`include "uvm_macros.svh"

package uvm_pkg;

  `include "dpi/uvm_dpi.svh"
  `include "base/uvm_base.svh"
  `include "tlm1/uvm_tlm.svh"
  `include "comps/uvm_comps.svh"
  `include "seq/uvm_seq.svh"
  `include "tlm2/uvm_tlm2.svh"
  `include "reg/uvm_reg_model.svh"

endpackage

`endif

In reply to susharma:

How did you compile spi_test_lib_pkg? Packages must be compiled before they can be imported.

Hello Dave,

I am using Questasim-10.2c, I have all the files of SPI-APB from VA(in uvm) on the left panel including .v, .sv and .svh.
I just right click that panel and ->compile ->compile order → Auto generate-> ok.

I trying to import or include the file uvm_reg.svh and uvm_reg_map.svh in my environment.
But it gives error.

**Could not find the package (uvm_reg). Design read will continue, but expect a cascade of errors after this failure. Furthermore if you experience a vopt-7 error immediately before this error then please check the package names or the library search paths on the command line.

Can you try changing this

`include "C:/questasim_10.2c/verilog_src/uvm-1.1d/src/reg/uvm_reg.svh"

to

`include "uvm_reg.svh"

add just add an +incdir to search for that file…

In reply to Sushrut Veerapur:

Hello Sushrut,

Thanks for the workable effort. I have done one thing.

In uvm_pkg::*;, I have added the path of uvm_reg.svh, uvm_reg_map.svh file. Now it is working. With your approach, it is compiling uvm_reg.svh file completely and produce more errors.
I am not sure whether above hack is ok or not.
One more query, any reg file in uvm that accepts typedef struct packed as parameter, in the first class above , it is giving error in uvm_register(word_t) line.

Thanks and Regards
Sunil

cgales · April 15, 2015, 1:04pm

In reply to susharma:

You don’t ever want to include uvm_reg.svh or any other UVM source code file within your code. All of the UVM code is pre-compiled as part of the uvm_pkg. You will only ever need:

import uvm_pkg::*;
`include "uvm_macros.svh"

in all of your UVM based code. Note that there is no path specified in the uvm_macros.svh include directive. Importing uvm_pkg::* will provide access to all of the UVM classes, including the uvm_reg. There is no specific uvm_reg::* package.

If you include UVM source code directly in your package, you will cause multiple definitions and havoc will ensue.

Hello Cgales,

My environment is using the file like::->

And when I change the name, to uvm_reg_map, it gives error of,

I am trying to simulate SPI-APB uvm-1.1d environment in Questasim-10.2c.

Please help and guide.

Can you post your code and the exact error message that is given. It’s not clear what you are trying to accomplish. Are you trying to extend uvm_reg_map? How are you trying to do that?

In reply to susharma:

There is no uvm_register_pkg. All of the UVM register functionality is contained within the uvm_pkg. That is why importing is is failing.

Is this an example from the Verification Academy. If it is, then we will need to look at updating it to the latest register implementation. There might be a few examples that use the old style that haven’t been updated.

Read the UVM Cookbook chapter on UVM Registers for the current implementation.
