System-Level FDTD EM with Test-Measurement Accuracy
Cadence Clarity 3D Transient Solver
3D finite-difference time-domain (FDTD) EM simulation for electrically-large systems. Tackle EMI / EMC compliance, antenna placement, SAR, and biomedical analysis with 10X speed and capacity — and test-measurement accuracy.
Overview
Unmatched Speed & Capacity in EM Simulation
The Clarity 3D Transient Solver is a 3D FDTD EM simulation tool for complex systems and subsystems. It addresses the most demanding EM challenges in 5G, automotive, HPC, and machine-learning applications with test-measurement accuracy.
Used for EMC compliance, susceptibility, antenna placement, biomedical analysis, and more. Produces voltage, current, field distribution, and field animation in the time domain — and SAR, near/far-field distribution, current distribution in the frequency domain.
Key Benefits
Multiprocessing for the Most Complex Systems
Tackle full-system analysis with test-measurement accuracy.
10X Faster Analysis
Up to 10X faster than legacy 3D FDTD field solvers — without giving up test-measurement accuracy.
10X Capacity
Up to 10X capacity for true system-level analysis — multi-board, multi-package, chassis-included.
Save Design Time
Parallelize across multi-core compute; complex structures resolve 10X+ faster than before.
Lower Cloud Cost
Cloud-based servers solve 3D structures at lower compute cost than premium on-prem hardware.
Cloud & On-Prem
Runs on hundreds of CPUs or multiple GPUs — optimized for both cloud and on-premises distributed compute.
Features
Enhanced Parallelization & Integrated Solutions
Breakthrough Parallelization
Flexibility for engineering managers when budgeting compute configurations for 3D simulation.
Test-Measurement Accuracy
Brings 3D accuracy analysis to engineers responsible for system-level compliance.
Maximize Resources
No early termination from exhausted compute — solver scales down to small core counts too.
All Design Platforms
Reads design data from all standard chip, IC package, and PCB platforms; imports MCAD mechanical structures from all major tools.
Integrated 3D Solutions
Integrates with Allegro X APD Layout, Virtuoso environment, and Allegro X PCB Design — optimize in analysis, implement in design, no redrawing.
EM Interface Models
Merge mechanical structures (cables, connectors) with the system design and model an EM interface as a single model.

Capabilities
Computational Edge for Faster Designs
Save Design Time
Parallelization Built In From Day One
Historically, large systems were analyzed at the subsystem level with full-system results coming from prototypes. Clarity 3D Transient was designed from the ground up to take advantage of multicore compute by parallelizing the mathematical work required to solve for 3D structures.
Tasks parallelize within one machine's cores or across many — cutting time to solve for complex structures by 10X or more. The time required scales nearly linearly: double the cores, double the throughput.
Cost Savings via Cloud
Cheaper Solves on Cloud Infrastructure
Web-based cloud servers are an alternative to buying compute hardware. Instead of large, expensive servers, select lower-cost cloud compute — and still maintain the highest performance.
The result: considerable savings on the cost of cloud compute for 3D-structure solves, with no compromise on engineering throughput.
