Gold-Standard 3D Electromagnetic Simulation
Cadence Clarity 3D EM Solver
Tackle the most complex EM challenges in 5G, automotive, HPC, ML, and antenna design with gold-standard accuracy. Massively-parallel architecture delivers virtually unlimited capacity and 10X speed — with simulation that matches lab measurement at 112 Gbps+.
Overview
3D EM Analysis for IC, PCB, Package & Complete Systems
The Cadence Clarity 3D Solver is a 3D electromagnetic simulation tool for designing critical interconnects across PCBs, IC packages, and systems-on-IC (SoIC) — the kind of high-frequency designs found in 5G, automotive radar, HPC, and antennas where gold-standard accuracy is mandatory.
Cadence's industry-leading distributed multiprocessing technology delivers virtually unlimited capacity and the 10X speed needed to address larger, more complex structures. Highly accurate S-parameter models — and time-domain field results — feed SI, PI, RF/microwave, and EMC analysis with confidence even at 112 Gbps+ data rates.
Why Clarity
Speed, Accuracy, Capacity & Streamlined Workflows
EM simulations are costly. Clarity removes the trade-off between accuracy and turnaround — no more fracturing the design, no more stitching results back together.
Stay in Your Design Flow
Seamlessly integrated with Cadence Virtuoso, Allegro SiP, and Allegro X PCB Designer — the design flow is repeatable, scalable, and traceable, with no jumping between databases.
Massively-Parallel Engine
State-of-the-art parallelized matrix solver with breakthrough adaptive mesh and frequency-sweep algorithms. Near-linear scalability with gold-standard accuracy for sign-off and manufacturing.
Customizable & Scalable
Clarity 3D Solver Cloud offers cloud-optimized distribution, dynamic deployment, fault-tolerant restart, and cost-priority scheduling — security, stability, and unbounded capacity.

What Clarity Brings to Your Design Flow
Massively-Parallel Simulation
Industry-leading Cadence distributed multiprocessing — virtually unlimited capacity and 10X speed. Match available compute to the size of the design.
Seamless Cadence Integration
Integrated with Allegro, Virtuoso, and AWR platforms — optimize in the analysis tool, implement in the design tool, no redrawing.
Parallel Matrix Solver
Meshing and frequency sweep both partitioned and parallelized across every computer, configuration, and core that's available.
Cloud-Optimized Distribution
Massively-parallel architecture gives elastic access to multiple cores in the cloud for unbounded simulation capacity.
Performance & Signoff
Virtually linear performance gain, up to 10X speedup over current solutions; fine-tuned FEM algorithms preserve golden accuracy.
S-Parameter Extraction
Gold-standard S-parameter accuracy for signoff-level confidence in PI, SI, and high-frequency RF / microwave applications.
Accurate Models Faster
Where Clarity Delivers
IC Packages
Stacked die, higher pin counts, tighter electrical constraints. EM solver integration with Allegro Package Designer Plus + SiP Layout Option gives a seamless flow with signoff accuracy.
PCBs
Dense multi-domain PCBs (digital, analog, RF, optical) must coexist on a small footprint. Cadence EM accurately characterizes the environment — eliminating respin.
Connectors
PCB-to-SMA RF connectors can introduce unwanted HF effects. Import MCAD connector models and mate them with PCB designs to mitigate or eliminate them.
Antennas
Multi-protocol radios (Wi-Fi, BT, GSM, GPS, V2V) demand EM simulation to maintain connectivity while preventing inter-protocol interference.
