Evolving Design Processes for Highly Optimized ICs, PCBs, and Systems
As the electronics industry continues to push the boundaries of innovation, design processes are evolving rapidly to meet the demands of increasing complexity. The traditional approach of designing, simulating, and iterating is no longer sufficient. Designers are now exploring the potential of integrating machine learning (ML) and artificial intelligence (AI) techniques to enhance the design exploration and validation process. By leveraging the vast amount of design data available, ML and AI have the potential to revolutionize electronics design. In this article, we will explore the concept of in-design analysis, the role of ML techniques, and the future implications for the industry.
In-Design Analysis: Shifting Left and Thinking Systemically
The current design process involves producing a design, simulating it, and making adjustments based on the results. However, as design complexity increases, this approach becomes challenging. To address this, electronic design automation (EDA) vendors are working towards enabling in-design analysis capabilities earlier in the design flow. This shift left approach allows designers to analyze and optimize designs more systemically. For example, they can analyze the integrity of a signal as it traverses various components, such as ICs, packages, and PCBs. In-design analysis brings forward cross-domain constraint violations and highlights optimization opportunities, empowering designers to make informed decisions.
ML Techniques: Enhancing Design Exploration and Optimization
ML techniques can play a crucial role in expanding the design space and optimizing designs. Generative ML techniques, for instance, can generate design options based on a model trained on the physics of multiple candidate designs. As each candidate design is simulated, the data is fed back to the model for reinforcement learning, leading to the generation of better designs. Cadence’s Optimality Intelligent System Explorer tool exemplifies this approach, helping designers navigate the vast system design space and overcome the “tyranny of choice.” ML techniques enable designers to explore and optimize designs efficiently, even in domains they may not be familiar with.
Collaborative Design: The Future of Electronics Design
The next step in applying ML to electronics design involves leveraging the vast design datasets available to extract patterns that represent cues for design success or warnings of failure. This collaborative design approach involves a designer working alongside an AI “co-pilot” to explore a design space constrained by patterns revealed through ML analysis. Instead of relying solely on simulation tools, designers can benefit from helper applications that provide insights based on successful designs. While the implementation of such co-pilots is still in progress, Cadence has developed the Joint Enterprise Data and AI (JedAI) Platform, which utilizes ML and AI to enhance electronics design.
Conclusion:
The integration of ML and AI techniques into electronics design processes holds immense potential for the industry. In-design analysis allows designers to think more systemically and optimize designs across domains. ML techniques enable efficient design exploration and optimization, expanding the design space. The future of electronics design lies in collaborative efforts between designers and AI co-pilots, leveraging ML analysis to guide design decisions. As the industry continues to evolve, embracing these advancements will be crucial in keeping global innovation on track.
