Cadence unveils platform to slice EMI simulation costs

Cadence Design Systems is aiming to ease the frustrations of customers seeking to meet EMI emissions compliance.

The launch heeds the call from customers who have either gone for what Brad Griffin, Product Management Group Director, Multi-Physics System Analysis at Cadence describes as the “throw spaghetti at the wall approach” or make the product and hope it complies, or built prototypes and then hired expensive test chambers to ensure compliance. Either approach can take longer and be costly.

The solution launched at the CadenceLIVE Europe event is Clarity 3D Transient Solver which says Griffin “delivers a 10 times faster system-level EMI simulation.”

“The architecture allows the solver to run on hundreds of CPUs to be optimised for both cloud and on-premises distributed computing,”

He cites numerous applications including automotive where the platform can be used to simulate both the emissions and immunity of engine control units (ECUs).

Says Griffin, “For consumer applications Calrity 3D transient Solver will optimise antenna placement on a PCB

to ensure data reliability in wireless transfers.”

Griffin also instanced healthcare where the platform will ensure adherence to strict Class A or B CISPR (Comité International Spécial des Perturbations Radioélectriques) compliance standards.

The 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 is based on proven, proprietary Cadence distributed multiprocessing technology that spreads computing resources over hundreds or even thousands of cores in cloud-based compute environments.

The Cadence CloudBurst platform offers a path to a hybrid cloud environment for IC and system development.

Says Brad Griffin, “It’s web-based so it doesn’t require a customer IT setup. It allows high-throughput file transfer for huge design files.”

“It is ideal to deliver the cloud-ready Cadence Clarity 3D Transient Solver,” he adds.

The Clarity 3D Transient Solver also offers integration with Cadence VirtuosoLayout, Allegro PCB Designer and SiP Layout.

“As a premier engineering service provider, Ultimate Technologies focuses on quick, efficient and first-time-right designs,” said Satoshi Utsumi, CEO of Ultimate Technologies, Inc. “The Clarity 3D Transient Solver from Cadence allows us to simulate with test-measurement accuracy so we can predict what will be measured during EMI testing, thereby ensuring our customers pass EMI compliance checking on the first pass while dramatically reducing the number of prototype designs. This allows us to shave up to three months off automotive ECU design cycles, reducing design cycle time by as much as 30%. With Clarity 3D technology, we can quickly iterate and improve design quality while meeting customer schedule demands.”

The Clarity 3D Transient Solver supports Cadence’s Intelligent System Design strategy, enabling system innovation. It is expected to be available in the first quarter of 2021
