Discover how MediaTek utilized Cadence Optimality and Clarity 3D Solver to revolutionize their signal integrity design, achieving a massive 75X increase in design productivity.
In the move toward 5G and 6G, the interconnects between the PCB design and the package carry extremely sensitive signals. Suppressing or eliminating common signal integrity problems is no longer just a task — it’s a necessity.
Traditionally, the process relied heavily on human intuition and exhaustive back-and-forth communication between analysis and layout teams. Designers had to manually identify and adjust parameters for impedance matching, routing, and stub design based on individual simulation results.
MediaTek addressed these bottlenecks by integrating a generative ai driven Multiphysics solution into their flow. The synergy between Cadence Optimality Intelligent System Explorer and the Clarity 3D Solver creates a self-optimizing loop :
1. Automated Exploration : Optimality uses AI to explore the design space with a high degree of freedom, identifying optimal parameters for impedance matching and tolerance.
2. High-Fidelity Solving : The Clarity 3D Solver provides the underlying electromagnetic accuracy, focusing on critical frequency domain indexes such as insertion loss, return loss, and crosstalk.
3. Frequency Domain Gains : The AI-driven approach targets specific SI indexes like SCD21 and near-end/far-end crosstalk. By leveraging this multi-target approach, MediaTek achieved a 27% improvement in far-end crosstalk optimization and a 60% improvement in return loss.
The true value of this AI integration isn't just the performance of the silicon, but the efficiency of the engineers:
By automating the SI channel optimization, MediaTek increased productivity by 75 times compared to traditional package design flows.
The AI drastically reduces the "guesswork" communication between layout and analysis teams.
With the AI providing the "answers," both junior and senior engineers spend more time understanding the design principles behind the optimization rather than simply repeating simulation tasks.
