Realtek has adopted a leading-edge and user-friendly electromagnetic (EM) simulation workflow developed by Ansys to accelerate complex RFIC design and improve efficiency by shrinking silicon area. Realtek uses RaptorH's silicon-optimized modeling flow to substantially decrease simulation time and reduce wasteful overdesign by accurately predicting EM coupling in applications ranging from RFIC and high-speed IC to cutting-edge Internet of Things products. RFIC advanced node designs must manage the growing challenge of EM interference caused by high-frequency, millimeter wave signals and occurring across different RF blocks. To improve the efficiency of design margins, Realtek IC designers rely on Ansys? RaptorH?'s large capacity engine to analyze complete circuit blocks with high fidelity. By adopting this silicon-optimized modeling flow, Realtek designers are accelerating EM modeling times by 3x ? 10x. Additionally, they are shrinking silicon real estate by drastically reducing block-to-block EM crosstalk in extremely complex designs.
