Electronic design automation (EDA) or computer-aided design (CAD) is a category of software tools for designing electronic systems, such as integrated circuits (ICs). By EDA tools, designers can finish the design flow of very large scale integrated (VLSI) chips with billions of transistors. EDA tools are essential to modern VLSI design due to the large scale and high complexity of electronic systems.

Recently, with the boom of artificial intelligence (AI) algorithms, the EDA community are actively exploring AI for IC techniques for the design of advanced chips. Many studies have explored machine learning (ML) based techniques for cross-stage prediction tasks in the design flow to achieve faster design convergence. For example, Google published a paper in Nature in 2021 entitled A graph placement methodology for fast chip design, leveraging reinforcement learning (RL) to place macros in a chip design. The basic idea is to regard the chip layout as a Go board, while each macro as a stone. In this way, an RL agent can be pre-trained with 10,000 internal design samples and learn to place one macro at a time. By finetuning the agent on each design for around 6 hours, it can outperform the performance of conventional EDA tools on Googles TPU chips, and achieve better performance, power, and area (PPA).

It can be seen that AI for EDA is being actively explored in the design automation community. Although building ML models usually requires a large amount of data, most studies can only generate small internal datasets for validation, due to the lack of large public datasets and the difficulty in data generation. To this end, an open-source dataset dedicated to ML tasks in EDA is urgently desired.

To address this issue, the research group from Peking University has released the first open-source dataset, called CircuitNet, which is dedicated to AI for IC applications in VLSI CAD. The dataset consists of over 10K samples and 54 synthesized circuit netlists from six open-source RISC-V designs, provides holistic support for cross-stage prediction tasks, and supports tasks including routing congestion prediction, design rule check (DRC) violation prediction and IR drop prediction. The main characteristics of CircuitNet can be summarized as follows:

To evaluate the effectiveness of CircuitNet, the authors validate the dataset by experiments on three prediction tasks: congestion, DRC violations, and IR drop. Each experiment takes a method from recent studies and evaluates its result on CircuitNet with the same evaluation metrics as the original studies. Overall, the results are consistent with the original publications, which demonstrates the effectiveness of CircuitNet. A detailed tutorial about the experimental setup is available on the webpage (https://circuitnet.github.io/). In the future, the authors plan to incorporate more data samples with large-scale designs in advanced technology nodes to improve the scale and diversity of the dataset.
