Ansys VeloceRF vs. Ansys Exalto

Ansys VeloceRF streamlines the design workflow by drastically reducing the time needed to synthesize and model complex spiral devices and transmission lines. Users can generate geometries for inductors or transformers in seconds, with modeling and analysis completed in just a few minutes. The software is designed to integrate effortlessly with leading EDA platforms, enabling the creation of layouts that are ready for tape-out. With Ansys VeloceRF, engineers can design devices featuring tightly packed components and lines, leading to a more efficient silicon layout. By evaluating the coupling between different inductive devices before delving into detailed layouts, it helps reduce the design footprint and may even do away with the necessity for guard rings. The size of inductors and the crosstalk among them can greatly influence the overall die size, and Ansys VeloceRF facilitates the development of smaller components through the application of optimization criteria and geometry constraints. Additionally, it examines the coupling between multiple inductors to optimize silicon space and boost the performance of inductors within the circuit, ensuring a more effective and efficient design process. This advanced feature not only increases the accuracy of designs but also simplifies the workflow for engineers managing intricate circuit layouts, ultimately leading to faster project completions and improved outcomes.

Ansys Exalto is a specialized software tool for post-LVS RLCk extraction that aids integrated circuit (IC) designers in accurately detecting unknown crosstalk across different design hierarchy blocks by extracting lumped-element parasitics and establishing a precise model for electrical, magnetic, and substrate interactions. This tool is designed to work seamlessly with most LVS tools and can significantly improve the RC extraction capabilities of your chosen software. By leveraging Ansys Exalto’s post-LVS RLCk extraction features, IC designers can proficiently predict electromagnetic and substrate coupling effects, allowing for the signoff of circuits that were once considered "too large to analyze." The models produced by the software can be back-annotated to the schematic or netlist, ensuring compatibility with all circuit simulators. As the demand for RF and high-speed circuits grows in modern silicon systems, accurately modeling electromagnetic coupling has become increasingly vital, as it plays a crucial role in the success of silicon designs. Therefore, Ansys Exalto proves to be an indispensable tool for designers striving to tackle the intricate challenges of contemporary circuit design with utmost accuracy and efficiency. Furthermore, its capabilities not only streamline the design process but also enhance the reliability of the final product, making it a valuable resource for any IC design team.
