Engineers can extract highly accurate S, Y, and Z-parameters across broad frequency sweeps. The software ensures passivity and causality in the exported datasets, making them ready for seamless time-domain circuit simulation in external SPICE tools. High-Utility Target Applications
: Real-time geometry adjustment using the FastEM Design Kit allows users to tweak dimensional parameters and instantly view shifted resonance points without starting a full matrix re-solve.
Do not pursue cracked IE3D. Instead, consider:
: Uses an integral equation 3D full-wave EM simulation technique to provide high accuracy for planar and multi-layer structures. High-Frequency Modeling
While IE3D has supported GPU acceleration since v14, v15.127 introduces . It now leverages NVIDIA’s CUDA 11.x architecture and AMD’s ROCm stack. For a large problem (e.g., a 20-layer PCB with 500+ ports), the solver can distribute the matrix filling and iterative solution across four GPUs, achieving a 4.7x speedup over CPU-only simulation.
We tested against the previous build (v15.110) on three standard benchmarks.
The software is organized into three primary executables that handle the design workflow:
Use cases
The cooling fans in the workstation kicked into high gear. Usually, the progress bar crawled like a tired insect. Today, it sprinted. The "new" engine in V15 wasn't just faster; it was efficient in a way that felt almost predatory. It solved the green's functions with an elegance that Aris had never seen in previous versions. 📡 The Ghost in the EM Field
