In the Chipyard root, run:
In the Chipyard root, ensure that you have the Chipyard conda environment activated. Then, run:
.. code-block:: shell
./scripts/init-vlsi.sh sky130
to pull the Hammer & plugin submodules. Note that for technologies other than ``sky130`` or ``asap7``, the tech submodule must be added in the ``vlsi`` folder first.
Pull the Hammer environment into the shell:
.. code-block:: shell
cd vlsi
export HAMMER_HOME=$PWD/hammer
source $HAMMER_HOME/sourceme.sh
to pull and install the plugin submodules. Note that for technologies other than ``sky130`` or ``asap7``, the tech submodule must be added in the ``vlsi`` folder first.
