Ansys SIwave™ Solutions in HFSS 3D Layout
Ansys SIwave™ is a printed circuit board (PCB) and package electromagnetics simulation software for power-ground plane and signal integrity analysis. It employs a powerful full-wave analysis engine to generate both frequency-domain and time-domain results. Using the highly optimized internal field solver, SIwave simulates complete board/package designs with full-wave accuracy. Simulation results can be reported graphically using advanced 2D and 3D plotting methods. For more information about the standalone SIwave product, consult SIwave help.
Only the Ansys SIwave™ DC IR Solver is currently available through the IC Mode environment.
HFSS 3D Layout contains the following SIwave solution types:
- SIwave SYZ Solver – a high-speed hybrid solver for medium and large-scale analysis of PCBs and packages, the SIwave SYZ Solver calculates frequency-dependent S-parameters for signal integrity and EMI investigations, and board-level power supply impedance modeling.
- Near Field Solver – a solver for analyzing the near-field region of PCBs and packages, which calculates electromagnetic fields and currents to assess near-field EMI, crosstalk, and impedance effects, ensuring optimal signal integrity and electromagnetic compatibility (EMC).
- SIwave DC IR Solver – solves for voltage drop across the power plane and provides important information pertaining to power delivery.
To complete these solutions from General mode, begin with the SIwave Workflow Wizard, then follow the specific steps for the solver.
