The OpenROAD chat assistant aims to provide easy and quick access to information regarding tools, responses to questions and commonly occurring problems in OpenROAD and its native flow-OpenROAD-flow-scripts.
The current architecture uses certain retrieval techniques on OpenROAD documentation and other online data sources. We aim to continuously improve the architecture and the associated the dataset to improve accuracy, coverage and robustness.
- Installation and Troubleshooting Assistance: The chatbot will provide users with quick and accurate solutions to common installation issues and troubleshooting steps.
- Easy Access to Existing Resources: The chatbot will be able to summarizing relevant information from OpenROAD documentation, user guides, and online resources to provide concise and actionable answers to user queries.
Build manpages as per the instructions here. Place the markdown files in backend/data/markdown/manpages
before proceeding.
Ensure you have docker
and docker-compose
installed in your system.
- Step 1: Clone the repository:
git clone https://github.com/The-OpenROAD-Project/ORAssistant.git
- Step 2: Copy the
.env.example
file, and update your.env
file with the appropriate API keys. Get the Google Gemini API Key and add it to your env file, add other env vars as required.
cd backend
cp .env.example .env
- Step 3: Start the server by running the following command:
docker compose up
- Prerequisites: Python 3.12, recommended to use a virtual environment like
conda
. - Step 1:
pip install -r backend/requirements.txt
- Step 2: Copy the
.env.example
file as shown above. - Step 3: To scrape OR/ORFS docs and populate the
data
folder, run:
cd backend && python scrape_docs.py
- Step 4: To run the server:
python main.py
Currently, documentation from OpenROAD and OpenROAD-flow-scripts is chunked recursively and embedded into FAISS Vector Databases.
Documents are first retrieved from the vectorstore using a hybrid retriever, combining vector and semantic search methods. These retrieved documents undergo reranking using a cross-encoder reranker model.
Then top-n documents from the reranked set are then sent to the LLM as input context, for generating a response.
flowchart LR
id0([Query]) --> id1
id1([Vectorstore]) --- id2([Semantic Retriever])
id1([Vectorstore]) --- id3([MMR Retriever])
id1([Vectorstore]) --- id4([BM25 Retriever])
id2([Semantic Retriever]) -- Retrieved Docs ---> id5([Reranking])
id3([MMR Retriever]) -- Retrieved Docs ---> id5([Reranking])
id4([BM25 Retriever]) -- Retrieved Docs ---> id5([Reranking])
id5([Reranking]) -- top-n docs --> id6([LLM])
The backend will then be hosted at http://0.0.0.0:8000.
Open http://0.0.0.0:8000/docs for the API docs.
