Sigrity PowerSI 3D EM Extraction Option

To accelerate your IC package and PCB power-integrity and signal-integrity analysis as well as electromagnetic interface (EMI)/electromagnetic compatibility (EMC) analysis, the Cadence^® Sigrity™ PowerSI^® 3D EM Extraction Option three-dimensional (3D) full-wave and quasi-static electromagnetic (EM) field solver provides S-parameter model extraction using model reduction technology. For accuracy with complex 3D structures, the cloud-ready tool features adaptive finite element mesh (FEM) refinement technology.

The standard 2D view of the design (left) allows for selecting nets and viewing individual or groups of nets. By walking through the steps in the workflows provided, you can follow a repeatable flow for common tasks. A 3D view of the design (right) allows you to track the connectivity through vias and visualize relationships between interconnects that would not be possible with only a 2D view.

The PowerSI 3DEM option incorporates a 3D mechanical CAD GUI for creating, editing, and importing 3D solid models for 3D electromagnetic analysis. You can bring in design data from popular MCAD formats such as Acis, IGES, and STEP, as well as the Cadence Allegro^®and Sigrity formats. 3D mechanical components are easily created with parameterization and equation expressions to allow for modeling flexibility and simulation optimization.

Along with a host of other features, the PowerSI 3DEM option enables you to create models for use in improved time-domain transient analysis, thanks to its robust low-frequency-conditioning algorithm, which gives you stable and accurate solutions down to 100Hz. The PowerSI 3DEM option has a workflow-driven user interface and component-based automatic port generation and grouping that makes it relatively easy for you to use.

The quasi-static extractor runs much faster than the full-wave technology, but makes certain assumptions (i.e., electric and magnetic fields are independent from each other). It quickly produces interconnect model results that consist of resistance (R), inductance (L), capacitance (C), and conductance (G).
