Multi-block EM Extraction Engineering Software

ANSYS RaptorH is a high-performance electromagnetic (EM) modeling and extraction solution developed by ANSYS for advanced semiconductor applications, including high-speed ICs, on-silicon designs, and 3D-IC integration. It combines the high-capacity RaptorX engine with the high-accuracy ANSYS HFSS solver to deliver both scalability and precision in EM analysis.

RaptorH enables designers to perform detailed multi-block electromagnetic extraction, allowing accurate analysis of complex integrated circuit (IC) layouts. This includes full-custom analog blocks, spiral inductors, transmission lines, power distribution networks, and clock trees—all within a unified and efficient workflow.

• Multi-Block EM Extraction: Analyze large and complex IC designs by partitioning them into manageable blocks while maintaining high accuracy.
• High-Speed Signal Integrity Analysis: Evaluate parasitic effects, coupling, and losses in high-frequency and high-speed circuits.
• 3D-IC & Advanced Packaging Support: Model through-silicon vias (TSVs), interposers, and stacked die configurations.
• On-Silicon EM Modeling: Accurately capture substrate effects and interactions critical for RF and mixed-signal designs.
• Scalable Workflow: Efficiently handle large-scale layouts with optimized memory usage and runtime performance.

RaptorH is widely used in the design and validation of RF, analog, and mixed-signal ICs, as well as high-speed digital systems. It is particularly valuable for applications such as:

• High-speed communication interfaces
• RF front-end modules
• Power grids and clock distribution networks
• Advanced semiconductor packaging and 3D integration

By leveraging the combined strengths of RaptorX and HFSS, ANSYS RaptorH enables engineers to:

• Achieve high-accuracy EM extraction for critical circuit blocks
• Reduce design iterations and silicon re-spins
• Improve signal integrity and power integrity
• Accelerate time-to-market for advanced semiconductor products
