In its new Clarity 3D transient solver, Cadence Design Systems provides a system-level simulation environment 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 challenge of system-level EMC/EMI compliance, from both the emissions and susceptibility standpoints, is an increasingly difficult one as end products become denser, data rates rise, and systems are equipped with more wireless connectivity. The new solver is capable of simulating large designs that until now have been impractical or unable to be solved, reducing re-spins and accelerating time to market. It’s particularly applicable in growth industries such as automotive, consumer electronics, and healthcare.

The Clarity 3D Transient Solver quickly and accurately performs large-scale simulations when designing critical interconnects for PCBs, IC packages, and system-on-IC (SoIC) designs within a mechanical enclosure. It relies on Cadence’s distributed multiprocessing technology that spreads computing resources over hundreds or even thousands of cores in cloud-based computing environments. As a result, designers can move beyond the module level to simulate entire systems at speeds up to 10X faster than legacy field-solver technology while maintaining verifiable accuracy. It means less time spent in 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 a high degree of integration with Cadence’s Virtuoso Layout, Allegro PCB Designer, and SiP Layout tools, so that issues that turn up in Clarity 3D simulations can be quickly implemented, avoiding lengthy design iterations in the signoff stage.

An early beta tester, Ultimate Technologies, has found the Clarity 3D transient solver highly effective in predicting what will be measured in EMI testing. As a result, the company reports that it’s been able to shave up to three months (or about 30%) from automotive-ECU design cycles.

The Clarity 3D transient solver is expected to be available in the first quarter of 2021. Cadence also offers its CloudBurst platform for a quick path to a hybrid-cloud computing environment.
