How to generate UVM code from YAML code?

UVM
1

Hi
I’m watching “UVMF, one bite at a time” course. I want to use one of the example YAML files included in the UVMF download package to automatically generate the corresponding UVM code. I need some guidance. I don’t know what to do with the YAML file. I installed Python but I still don’t know what to do with the ‘yaml2uvmf.py’ file: how to execute it and how to pass to it the example YAML file to be converted to UVM code. I would be grateful if I can get some instruction here, or a hint to a document which explains the procedure step by step.
Thanks

In reply to Farhad:

you want something like this :

python $UVMF_HOME/scripts/yaml2uvmf.py mem_if_cfg.yaml pkt_if_cfg.yaml predictor_components.yaml block_a_env_cfg.yaml block_a_bench_cfg.yaml -d ./unvmf_template_output

you pass all of the YAML files for your agents, environment and bench to the generator
-d speifies the output directory

If you look in the following folder:

$UVMF_HOME/docs/generator_tutorials/alu/yaml_config_files there is a .bat script showeing the command to run
The PDF in the alu folder walks you through a complete tutorial

hope that helps

Thank you, Graeme
I don’t know what I’m doing wrong, but when I do as you said above, I get the following error:
AttributeError: module ‘jinja2’ has no attribute ‘version’
Maybe I’m missing some other software or necessary step?
Thanks again for taking the time and answering my question.

Hi Frahd

what version of Python are you using ?

There is a README file in the $UVMF_HOME/templates/python folder which says the following:

If using Python 2, everything should work out-of-the-box as all required packages are
shipped with the installation:

  • yaml
  • jinja2
  • markupsafe
  • voluptuous

If using Python 3, the user is responsible for installing some of these packages:

  • yaml
  • jinja2
  • markupsafe

NOTE: It appears that these packages come as part of Anaconda Python3 so no further
installations should be required.

Thank you very much, Graeme. I installed Anaconda Python3, which solved my problem.
