Cadence Revolutionizes System Design with Optimality Explorer for AI-Based Electronic System Optimization

Cadence Design Systems, Inc. announced the Cadence® Optimality Intelligent System Explorer, which enables multidisciplinary analysis and optimization (MDAO) of electronic systems. After revolutionizing simulation and delivering multiple products with breakthrough performance and accuracy, Cadence focused on optimization, first introducing the disruptive Cadence Cerebrus™ Intelligent Chip Explorer, and now Optimality Explorer. Leveraging AI technology similar to that used in Cadence Cerebrus to achieve breakthrough results, Optimality Explorer delivers optimized designs on average 10x faster than traditional manual methods, with up to 100x speedup achieved on some designs. Optimality Explorer further extends Cadence’s leadership in system analysis by bringing to market an industry first: an AI-driven, MDAO-enabled, in-design multiphysics system analysis solution.

Cadence’s Clarity™ 3D solver for 3D electromagnetic (EM) analysis and Sigrity™ X technologies for high-speed Signal Integrity (SI) and Power Integrity (PI) analyzes are the first software to multiphysics systems analysis from Cadence to adopt Optimality Explorer. With Optimality Explorer, Clarity and Sigrity X solvers can dramatically improve designer productivity and efficiency by enabling design teams to explore the entire design space and quickly and efficiently converge on the optimal design.

Optimality Intelligent System Explorer offers the following advantages:

  • Design preview: Allows designers to quickly determine optimal electrical performance, avoiding suboptimal local minima and maxima, while mapping variations for additional consideration and exploration of the full design space
  • Improved productivity: Enables engineers and design teams to efficiently produce system-level optimized designs, improving productivity by an average of 10x over manual brute-force parametric table studies, with up to 100x speedup achieved on some designs
  • Easy to use interface: Flexible usage model allows customers to enable Optimality Explorer from Clarity and Sigrity X environments for fast MDAO invocation
  • Extensible solution: Enables customers to extend AI-based optimization to Cadence’s multiphysics technologies to create a complete compute software solution spanning simulation, optimization, and approval

“For years, system-level optimization has been extremely inefficient based on a human-intensive workflow of design/prototype/test/refinement and eventual manufacturing,” said Ben Gu, vice- President of R&D for the Multiphysics Systems Analysis business unit at Cadence. . “With Optimality Explorer’s MDAO capability, it is now possible to perform system-level optimization, from IC to package, PCB to system, in a fraction of the time and with the precision reference of Cadence.”

Customer Approvals

“In high-speed packaging design, it’s a cost-effective and performance-efficient process to optimize the design before shrinking. For our DDR package optimization process, Cadence’s Clarity 3D solver, powered by Optimality Explorer, allowed us to discover the best parameter configuration, meeting our design criteria in a significantly shorter amount of time, thus speeding up our time to market while allowing us to provide a more efficient solution. solution,” said Alan Zhu, vice president of hardware at Ambarella.

“The Clarity 3D Solver has delivered unparalleled speed and capability with proven accuracy throughout our next-generation Kunlunxin AI chip project. We use Clarity 3D Solver for large-scale channel modeling and optimization. speed. Now, using Cadence Optimality Explorer, we have reduced the time spent optimizing transmission line performance from hours to minutes. We were able to tune the physical parameters of a routing constraint of high-speed differential pair much faster than previous methodologies. The time saved can be used to optimize other parts of our design so that all critical interfaces operate at peak performance,” said Canghai Gu, Chief Architect Kunlunxin chips at Baidu.

“MediaTek is a leader in SerDes design and technology. Cadence Optimality Explorer and Clarity 3D Solver helped us improve the performance of our recent 112G PAM4 SerDes project by 75%. Optimal feedback and insertion loss, as well as TDR waveforms, were determined quickly and efficiently using Cadence’s breakthrough AI-driven optimization, accelerating design team productivity and, ultimately, the success of the final product,” said Aaron Yang and Howard Yin, design directors at MediaTek.

“As early adopters of the Cadence Optimality Intelligent System Explorer, we focused on its performance on a rigid-flex PCB with multiple via and transmission line structures. Optimality Explorer’s AI-powered optimization has allowed us to discover new designs and methodologies that we otherwise would not have achieved. Optimality Explorer adds intelligence to the powerful 3D Clarity solver, allowing us to achieve our performance goal with accelerated efficiency,” said Kyle Chen, Principal Hardware Engineer at Microsoft.
