Logic synthesis is among the necessary steps in designing digital circuits, by which high-level descriptions are became detailed gate-level designs. The event of ML algorithms is remodeling fields akin to autonomous driving, robotics, and pure language processing. Varied Machine studying approaches have been used to combine domains. These ML strategies have improved logic synthesis, together with logic optimization, expertise mapping, and formal verification. They’ve proven nice potential to enhance the effectivity and high quality of the logic synthesis steps, making them quicker and higher. Nonetheless, extra dependable datasets are wanted to proceed bettering these strategies.
The standard benchmarks have performed a serious position in growing EDA instruments and methodologies by offering a basis for testing, comparability, and enhancement. Datasets like OpenABC-D have been created for logic synthesis from these benchmarks. Nonetheless, these datasets are designed for particular duties and restrict their use in several machine-learning functions. It fails to protect the unique info in intermediate information, which makes it troublesome to adapt and refine datasets for brand spanking new challenges.
To beat these drawbacks, a gaggle of researchers from China carried out detailed analysis. They proposed OpenLS-DGF, an adaptive logic synthesis dataset technology framework designed to help varied machine studying duties inside logic synthesis. The proposed framework covers the three basic levels of logic synthesis: Boolean illustration, Logic optimization, and Expertise mapping. The great workflow contains seven steps, together with the uncooked file technology and the dataset packing. The framework includes seven steps, from the preliminary design enter to the ultimate dataset packaging. The primary three steps embrace preprocessing the enter design to generate the generic expertise circuit and its optimized AIGs. The additional steps produce intermediate Boolean circuits derived from these optimized AIGs, together with logic blasting, expertise mapping, and bodily design. The ultimate step packages these Boolean circuits into PyTorch format knowledge utilizing a circuit engine, facilitating environment friendly dataset administration.
The dataset technology course of creates optimized circuit designs by linked steps. Enter designs are standardized into GTG after which remodeled into AIG for optimization. A number of circuit variations are generated in six codecs, mapped for ASIC/FPGA designs, and analyzed for efficiency. Outputs are organized into PyTorch information for simple use and validation, making certain flexibility and effectivity. The Circuit Engine processes uncooked information right into a dataset utilizing the “Circuit” class, which defines nodes with attributes like sort, identify, and connections. It contains instruments for simulation and compatibility with ML frameworks like “torch geometry.” Recordsdata which might be saved in Verilog and GraphML codecs are loaded by way of NetworkX, and structured graphs are created.
The OpenLS-D-v1 dataset is designed utilizing quite a lot of benchmark designs like IWLS and OpenCores, containing numerous combinational circuits. It options Boolean networks with vast major inputs and outputs, and the circuits embrace arithmetic, management, and IP cores. Graph embeddings mix heuristic and Graph2Vec options for evaluation. The dataset contains 966,000 circuits, categorized into 46 designs with totally different Boolean community sorts and netlists for ASIC and FPGA functions. In comparison with OpenABC-D, OpenLS-D-v1 presents extra range, making certain higher illustration for machine studying duties.
The experiments used ten designs from the OpenLS-D-v1 dataset, together with ctrl, router, and int2float, extracting roughly 120,000 pairs for pair-wise rating. The coaching coated 70% of the information with an enter function measurement of 64, a hidden function measurement of 128, a studying price of 0.0001, a decay price of 1e-5, and a batch measurement of 32, reaching excessive prediction accuracy. For QoR prediction throughout three variants (unseen recipes, designs, and design-recipe combos), the Imply Absolute Share Error (MAPE) reached 4.31% for GraphSAGE, 4.43% for GINConv, and 5.09% for GCNConv, with space prediction outperforming timing prediction. In probabilistic prediction, the node embedding strategies like DeepGate lowered common prediction errors by as much as 75% and computation time by 56.89× in comparison with GraphSAGE, demonstrating robust efficiency and scalability in circuit optimization and prediction duties.
In conclusion, OpenLS-DGF helps varied machine studying duties and highlights its potential as a normal useful resource and standardized course of in logic synthesis. The OpenLS-D-v1dataset additional enhances this by offering a viable basis for future analysis and innovation. The OpenLS-DGF demonstrated its utility by implementing and evaluating 4 typical duties on OpenLS-D-v1. The outcomes of those duties validate the effectiveness and flexibility of the framework. In future instances, the effectivity of the technology move might be enhanced, and the precise machine-learning duties for logic synthesis might be benchmarked!
