New Cadence Clarity 3D Transient Solver Delivers up to 10X Faster System-Level EMI Simulation

System design teams can quickly and accurately simulate large and complex hyperscale, automotive, mobile, and aerospace and defense systems

Cadence Design Systems, Inc. expanded its system analysis product line with the introduction of the Cadence Clarity 3D Transient Solver, a system-level simulation solution that solves electromagnetic interference (EMI) system design issues up to 10X faster than legacy 3D field solvers and offers unbounded capacity. Built on Cadence’s massively parallel matrix solver technology, the Clarity 3D Transient Solver handles workload levels that previously required time-consuming and expensive anechoic test chambers to test prototypes for electromagnetic compatibility (EMC) compliance. The new solver is capable of simulating large designs that until now have been impractical or unable to be solved, reducing respins and accelerating time to market. This makes it ideal for many complex applications in the hyperscale computing, automotive, mobile, and aerospace and defense markets.

he Clarity 3D Transient Solver is capable of quickly and accurately performing large-scale simulations when designing critical interconnects for PCBs, IC packages, and system on IC (SoIC) designs within a mechanical enclosure. It relies on proven, proprietary Cadence distributed multiprocessing technology that spreads computing resources over hundreds or even thousands of cores in cloud-based compute environments. This unbounded capacity lets designers move beyond the module level to simulate entire systems at speeds up to 10X faster than legacy field solver technology while maintaining verifiable accuracy. This results in less time spent testing prototypes against EMI emissions and immunity standards such as those set by Comité International Spécial des Perturbations Radioélectriques (CISPR). The Clarity 3D Transient Solver also offers unparalleled integration with Cadence Virtuoso® Layout, Allegro® PCB Designer and SiP Layout.

“Many customers advise it is very time consuming and expensive to find problem areas in anechoic test chambers, and often those problems are challenging to isolate, identify and fix,” said Ben Gu, vice president of multi-physics system analysis in the Custom IC & PCB Group at Cadence. “Now they can rely on the power of computational software simulation to identify and fix problems earlier in the design cycle. The Clarity 3D Transient Solver demonstrates that Cadence continues to deliver industry-leading solutions that significantly speed electronic system design.”
