This is achieved in an environment that provides a high degree of automation. With the PowerSI approach, there is no need to segment designs before simulation. This eliminates cumbersome design preparation while also offering greater accuracy than evaluating a system a few components at a time, as required by approaches relying on tradi- tional 3D analysis. Flexible Workflow In Extraction mode, the PowerSI environment provides a convenient way to extract S, Z, and Y parameters of user- selected ports. With simulations in Spatial mode, the PowerSI approach facilitates AC analysis to assess voltage distribution across ground planes. Users can flexibly control observation locations to focus on areas of interest such as voltage levels between plane pairs and performance for specific frequency ranges. A variety of 2D and 3D visualization options enables rapid results assessment. PowerSI capabilities incorporate a task-focused workflow that can be customized to provide step-by- step guidance tuned for frequent analysis tasks and to establish defaults to guide new users. Proven Capability Designs today are called on to create quality products at the lowest possible cost. The PowerSI environment enables early issue detection and streamlines resolution. Early visibility into potential EMI issues complements PI and SI capabilities. Near- and far-field radiation is displayed along with 3D geometry information. With the PowerSI approach, designers can fully analyze and strategically tune their designs to increase market advantage, which is why the Sigrity advanced SI and PI solutions are used by nearly every major electronics company in the world.
