PowerSI is still the choice as a powerful tool for Signal and Power Extraction

The hybrid solver is the core field solver used by PowerSI. This is the same engine used in other Sigrity tools, such as OptimizePI. 

The solver comprises of three different solvers that run independently but communicate with each other at each time step or frequency point. This results in maximum efficiency with balanced accuracy.

• Plane/EM Solver considers coupling between vias, reflection from edges, resonances, power and ground voltage fluctuations, and metal/dielectric losses.
• Circuit Solver handles linear and nonlinear circuit components, including IBIS models and HSPICE transistor models.
• Transmission Line Solverincludes trace coupling, skin-effect loss, dielectric loss, and frequency dependent dielectrics.                                                                  

Using Sigrity PowerSI electromagnetic (EM) field solver technology, you can readily perform a broad range of studies to identify

• Trace and via coupling issues,
• Power/ground fluctuations caused by simultaneously switching outputs,
• Design regions that are under or over voltage targets.

PowerSI technology also lets you perform extraction of frequency-dependent network parameter models and lets you visualize complex spatial relationships.

To begin with, you might have heard that PowerSI can extract frequency-dependent S, Z, and Y parameters for package and board modeling for subsequent time domain SSN simulation.   It is not only for extraction, but many workflows are provided in the PowerSI.

Here are some of them

• Facilitates AC analysis to assess voltage distribution across ground planes
• Establishes power delivery network (PDN) guidelines for IC packages and boards
• Evaluates electromagnetic coupling between geometries to enable better component, via, and decap placement
• Anticipates energy leaks with near-field ration display
• Assesses decoupling capacitor strategies and verifies placement effects Enables broadband modeling including accurate DC performance characterization (patent pending)

When it comes to the cross-platform usage and working with other tools nothing can match PowerSI

• Integrates seamlessly with 3D solutions for IC packages and boards
• Optimized for flows with Cadence SiP Layout, Allegro^®Package Designer, and Allegro PCB Designer
• Readily used in Mentor, Zuken, and Altium flows, accepting a mix of CAD databases where needed for multi-structure design support
