Recognizing the convergence of RF and High-Speed Digital design, v15 enhanced its support for:
Previous versions of IE3D were limited by memory bandwidth when handling large matrix operations. Version 15 introduced optimized matrix solvers that leverage modern multi-core CPU architectures more effectively. zeland ie3d v15 127 new
Open your old v14 or v15.0 projects. Re-mesh them using the adaptive meshing based on curvature and port resolution (new in .127). This automatically increases mesh density near ports and sharp bends, reducing S-parameter ripple. Recognizing the convergence of RF and High-Speed Digital
At millimeter-wave frequencies, surface roughness and copper grain effects dominate loss. v15.127’s Huray model provides accurate insertion loss predictions that align with VNA measurements within 0.1 dB/cm. Re-mesh them using the adaptive meshing based on
We tested zeland ie3d v15 127 new against the previous build (v15.110) on three standard benchmarks.
| Test Case | v15.110 (Time / Memory) | v15.127 (Time / Memory) | Improvement | |-----------|------------------------|-------------------------|--------------| | Microstrip bandpass filter (5-10 GHz) | 12 min / 1.8 GB | 7.5 min / 1.2 GB | 38% faster, 33% less RAM | | 4x4 patch antenna array (2.45 GHz) | 58 min / 4.2 GB | 22 min / 2.9 GB | 62% faster (GPU on) | | Differential via transition (28 Gbps SERDES) | 32 min / 3.1 GB | 18 min / 2.0 GB | 44% faster |
Conclusion: The new adaptive mesher + GPU acceleration make v15.127 the most efficient IE3D build to date.
