Keysight Technologies introduced an electronic design automation (EDA) software suite for silicon developers working on millimeter wave (mmWave) and subterahertz (sub-THz) frequency capabilities for 5G mmWave and 6G products.
New PathWave ADS 2024 design capabilities include:
- Faster second-generation 3D-EM and 3D-Planar meshing and solvers – Delivers algorithm enhancements taking superior advantage of domain knowledge about microwave structures and processes. Mesh optimization and layout and connectivity improvements reduce problem sizes for faster simulations. Solver enhancements also speed simulation by up to 10 times and require less specialized user expertise over a wider range of problems, including mmWave design at automotive radar frequencies of 79GHz. Open workflows save database management and reduce overhead from iterative, manual setup.
- Advanced layout and verification features – Enables design sign-off directly from ADS for LVS, LVL, DRC, and ERC for MMICs, as well as streamline productivity for module and multi-technology assembly. Wavetek is the latest foundry to fully support ADS for an end-to-end workflow.
- Electrothermal enhancements accelerate validation – Drives higher reliability and higher operating performance with validation of dynamic device operating temperatures under different bias and waveform conditions. Supports high-performance compute acceleration and up to 100 times transient speed-up using W3051E Electrothermal Dynamic Re-use, enabling higher test plan coverage and earlier insights in the design phase.
- Custom workflow support with expanded Python APIs – Increases flexibility and scalability. A load-pull data import utility, ANN modeling, and Python automation scripting for 5G power amplifier designers unlock new application potential to create targeted personalities of ADS.
Doug Jorgesen, Vice President of Applications, Marki Microwave, said: “We use PathWave ADS for our mmWave power amplifier designs because it is a complete integrated solution that gives us simulation models, layout tools, and the accuracy we need to ensure first pass success. ADS has a unique Winslow Probe stability analysis capability that enables us to optimize our amplifier designs with confidence. Our simulations closely match our lab measurements, so we avoid expensive prototype re-spins on our designs. ADS is our preferred tool for power amplifier design.”
Joe Civello, PathWave ADS Product Manager at Keysight, said: “Traditional RF/uW EDA workflows involve a variety of specialized solvers that require database transfers, deep domain knowledge, and familiarity with multiple environments. We’ve added more speed and performance to ADS electromagnetic (EM) meshing and solving algorithms to improve sweeping coverage through parameters like process variations and layout effects. RFPro in PathWave ADS 2024 streamlines workflows into a unified circuit-EM co-design cockpit where circuit designers can now perform EM simulation to tune and optimize designs early in the development cycle. ADS supports multi-technology design and analysis of thermal, EM, and layout parasitics on circuits and signal modulation. It enables rapid assembly of circuits, MMICs, packaging, interconnects, and module layouts to significantly improve mmWave engineering productivity.”
