BAG3 workspace for SkyWater130

Read the BAG3 documentation for initial server setup instructions, and basic tutorial scripts.

Instructions:

1. Log into to any compute server that supports RHEL7.
   • (BWRC users) All machines on the LSF cluster should now support RHEL7
2. Start bash or zsh. Note that tcsh is not supported.
3. Clone this repository and cd into it.
4. Initialize all submodules by running git submodule update --init --recursive
5. source .bashrc
6. Run ./init_files.sh to create a new cds.lib and set up symbolic links.
7. Compile the C++ back-end in pybag as follows:
   • cd BAG_framework/pybag
   • ./run_test.sh
   • cd ../..
8. Launch virtuoso.
9. Run BAG commands from the bash or zsh shell.

Note: Steps 3, 4, and 6 only need to be done when creating a new BAG workspace.

Note: Step 7 needs to be done when creating a new BAG workspace or when pybag is updated.

For typical operation (i.e., with a BAG workspace that is already set up and no pybag updates), do the following:

1. Log into to any compute server that supports RHEL7
2. Start bash or zsh.
3. cd into the workspace
4. Update all submodules by running git submodule update --init --recursive
5. source .bashrc
6. Launch virtuoso.
   • If you have a previously opened Virtuoso session in this workspace, run load("start_bag.il") in the CIW. This opens up the SKILL interface for BAG to import/export schematics and layouts.
   • A newly launched Virtuoso session will have this enabled already because start_bag.il is loaded in the .cdsinit.
7. Run BAG commands from the bash or zsh shell.
