1.2. Hammer Setup

Hammer has a few requirements and there are several environment variables to setup.

1.2.1. System Requirements

  • Python 3.6+ required
  • The ruamel.yaml package is recommended for key history (pip install ruamel.yaml)
  • python3 in the $PATH
  • hammer-shell in the $PATH
  • hammer_config, python-jsonschema-objects, hammer-tech, hammer-vlsi in $PYTHONPATH
  • HAMMER_PYYAML_PATH set to pyyaml/lib3 or pyyaml in $PYTHONPATH
  • HAMMER_HOME set to hammer repo root
  • HAMMER_VLSI path set to $HAMMER_HOME/src.hammer-vlsi

Sourcing hammer/sourceme.sh will setup the environment described above.

To check your environment you may run the following:

git submodule update --init --recursive
source sourceme.sh
cd src/test
echo $?

If the last line above returns 0, then the environment is set up and ready to go.

Note: certain tools and technologies will have additional system requirements. For example, LVS with Netgen requires Tcl/Tk 8.6, which is not installed for CentOS7/RHEL7 and below. Refer to each respective tool and technology’s documentation for those requirements.
