Shifting the Design Paradigm with In-Design Analysis and ML Techniques
The world of electronics design is evolving at a rapid pace, driven by the need for highly optimized integrated circuits (ICs), printed circuit boards (PCBs), and systems. To keep global innovation on track, design processes are embracing analysis techniques earlier in the exploration and validation phase. However, as design complexity increases, there is a growing need to go beyond traditional in-design analysis and leverage the power of machine learning (ML) and artificial intelligence (AI). This article explores the potential of integrating ML techniques into electronics design and how it can revolutionize the industry.
In-Design Analysis: A Paradigm Shift
Traditionally, the design process involved producing a design, simulating it, and iterating until it met the desired criteria. However, the combinatorial impact of increasing design complexity poses challenges to this approach. Furthermore, the need for optimizing ICs, boards, and systems as a unified entity adds another layer of complexity. Physical constraints that affect one aspect of the design can now impact other aspects as well. To address these challenges, the industry is moving towards in-design analysis, where design analysis capabilities are made available earlier in the design flow.
Systemic Design and Co-Optimization
In-design analysis empowers designers to think more systemically and enables cross-domain constraint violations to be identified earlier. Designers can now analyze the integrity of signals as they traverse various components, such as SerDes communications channels, from the transmitter IC silicon to the receiver IC silicon. This approach allows for a more holistic view of the design and highlights optimization opportunities. However, exploring this expanded design space efficiently can be challenging, particularly for designers who are not familiar with optimizing in other domains.
The Role of Machine Learning
Machine learning techniques offer a promising solution to address the challenges of exploring the expanded design space. Generative ML techniques can generate design options based on a model trained on the physics of multiple candidate designs. As each candidate design is simulated, the resulting data is used to update and improve the model through reinforcement learning. Cadence, for example, has implemented this approach in its Optimality Intelligent System Explorer tool, which helps designers navigate the vast system design space and overcome the “tyranny of choice.”
Collaborative Design with AI Co-Pilots
The next step in applying ML to electronics design involves leveraging the vast design datasets available to designers and tool providers. These datasets can be analyzed to extract patterns that indicate design success or failure. In this scenario, design becomes a collaborative effort between a designer and an AI “co-pilot.” The co-pilot, powered by ML and AI, assists the designer in exploring a design space constrained by the patterns revealed from ML analysis. Early design exploration is no longer solely driven by simulation tools but also by helper applications that provide insights based on successful design patterns.
Conclusion:
The integration of machine learning and AI into electronics design has the potential to revolutionize the industry. In-design analysis allows for systemic design and co-optimization, while ML techniques enable designers to efficiently explore the expanded design space. Collaborative design with AI co-pilots can further enhance the design process by leveraging the patterns extracted from vast design datasets. Although there is still progress to be made, the industry is already building the infrastructure and tools necessary to harness the power of ML and AI, keeping global innovation on track.
