Welcome to our guide on employing Deep Reinforcement Learning for optimizing logic synthesis! In today’s rapidly evolving tech world, efficient design space exploration is vital. However, the myriad of possible optimization permutations can be overwhelming. Here, we will walk you through the setup and running of the DRiLLS framework, designed to automate optimization processes autonomously.

Understanding the Concept: The Logic Synthesis Maze

Imagine navigating a massive maze where every turn leads to another decision point—this represents the design space exploration in logic synthesis. You must choose the right path (optimization sequence) to reach your goal (high-quality results). However, the maze branches out exponentially, making it challenging to explore all options. This is where our guide comes into play by introducing an Advantage Actor Critic (A2C) agent to help you navigate this maze, ensuring an efficient and autonomous journey through the convolutions of optimization.

Setup of DRiLLS

To utilize the DRiLLS framework, follow these steps:

• Install Necessary Software: Ensure you have Python 3.6, pip3, and virtualenv installed.
• Create a Virtual Environment: Run the command:

  virtualenv .venv --python=python3

• Activate the Environment: Execute the following command:

  source .venv/bin/activate

• Install Requirements: Run:

  pip install -r requirements.txt

  Note: This implementation is exclusively tested on Python 3.6 due to compatibility issues with TensorFlow 2.x.

Run the DRiLLS Agent

Now that your environment is set up, you’re ready to run the agent. Here’s how:

• Edit the params.yml file. Comments within will guide you through each field.
• Run the training process by executing:

  python drills.py train scl

• If you need help, just run:

  python drills.py -help

How DRiLLS Works

The DRiLLS framework consists of two significant components:

• Logic Synthesis Environment: This is where the design space exploration problem is set up as a reinforcement learning task. It is operationalized in files drillsscl_session.py and drillsfpga_session.py.
• Reinforcement Learning Environment: Here, the A2C agent works to find the best optimization at each given state. It is implemented in drillsmodel.py, utilizing drillsfeatures.py for feature extraction.

Troubleshooting

If you encounter any issues during the setup or execution of DRiLLS, here are some tips:

• Ensure that you are running Python 3.6, as later versions will not work with the current TensorFlow implementation.
• Double-check the paths for any files referenced in the script to ensure they exist.
• If you face installation problems, try reinstalling the virtual environment and re-running the pip install command.
