Trusted by industry leaders across semiconductors, telecommunications, aerospace, and beyond. Start using our Emerald simulation tool today.

EDA for the AI Era

Design with Confidence. Accelerate Your Roadmap.

CEMWorks offers a breakthrough simulation platform for modern electronic design automation (EDA), purpose-built to handle today’s most complex IC packaging, interconnects, and high-speed electronics challenges.

Where We Excel

  • Large Interconnects: Solve extremely complex geometries without the need to break problems into smaller domains. Our solver handles full-scale package simulations in a single pass.
  • Antenna-in-Package, Antenna-on-Chip, Chiplets, and AI Accelerators: Simulate next-gen architectures with full electromagnetic fidelity, including SIPI and EMC effects at system level.
  • High-Frequency, Electrically Large Systems: From chip-level to multi-board systems, our technology handles challenges that conventional tools struggle with.
  • 10–100x Faster Simulation: Thanks to our adaptive integral equation engine, designers achieve dramatic reductions in solve times without compromising accuracy.
  • Full-Wave High-Speed Characterization: Extract S-parameters and verify SI/PI/EMC behaviour across wide bandwidths from DC to the THz domain.

Easy Adoption, Seamless Workflow

Our Emerald simulation tool provides a streamlined user experience that bridges the gap between our advanced solver technology and conventional design flows. For scripting and automation, access our solver directly without a UI via scripting-only licenses.

  • Local or Cloud Licensing: Choose the deployment that fits your workflow - on-premises or cloud-based.
  • Complete Compatibility: Supports ODB++ and other major layout and 3D CAD formats.

Large Antenna Arrays

Model the Future of Wireless.

CEMWorks offers a breakthrough simulation platform for modern electronic design automation (EDA), purpose-built to handle today’s most complex IC packaging, interconnects, and high-speed electronics challenges.

Where We Excel

  • Phased Arrays & Antenna Arrays: Seamlessly simulate network parameters and EM-fields for large array structures with hundreds or thousands of elements in a single pass, no array factor approximations necessary.
  • Reconfigurable Intelligent Surfaces (RIS): Accurately model the behaviour of programmable metasurfaces in real-world deployment environments.
  • Electrically Large Structures: Confidently simulate structures where conventional solvers fall short.

Environmental Device Simulation​

Simulate the full picture.

Move beyond components. Simulate devices in complex environments, from indoor floor plans to outdoor cityscapes and the environment at large.

Where We Excel

Our environmental simulations (using Emerald) combine our state of the art solver with ray tracing capabilities to create custom, full-system workflows for:

  • RIS and Metasurfaces: Model both passive and active array surfaces in complex, large-scale environments, including transmission and reflection behaviors of incident waves.
  • Antenna Arrays: Simulate transmission, reception and general coverage of devices in complex, detailed environments

Flexible Workflow Integration

We work directly with your engineering teams to:

  • Integrate our solver into your existing toolchain.
  • Co-develop tailor-made workflows for specific applications.
  • Offer full support throughout your project lifecycle.
  • While a general-purpose UI is under development, our team provides hands-on collaboration to help you get started right away.

Our Solver Technology: AI-Driven Adaptive Integral Equations

A Different Kind of Engine.

At the heart of all our products is our proprietary adaptive integral equation (IE) solver. Built from the ground up to overcome the limitations of legacy FEM and FDTD approaches, our solver is redefining what’s possible in EM simulation.

What Sets Us Apart

Solves Maxwell’s Equations Natively using volumetric and boundary-based methods.

  • Targeted Refinement: Dynamically refines the solution where it matters most, maintaining accuracy while minimizing compute load.
  • No Domain Stitching: Model full systems in a single simulation without breaking them into disconnected regions.
  • Multi-scale Simulation: From micron-scale passives and vias to full interposer and board structures, our solver captures interactions across all scales in a single, coherent model.

Benefits of our Solver

  • Unparalleled Simulation Speed & Efficiency
  • Superior Accuracy for Electrically Large & High-Frequency Problems
  • Robust Across Use Cases from SIPI/EMC to antenna systems to environmental-scale problems
