Layout ExtractionANSYS SIwave can extract complete designs (which include multiple, arbitrarily shaped power/ground layers, vias, signal traces and circuit elements) with unprecedented accuracy and speed, without requiring potentially laborious layout partitioning by the user. SIwave extracts S-, Y-, and Z-parameters and IBIS interconnect models (ICM), displays 3-D electromagnetic fields, and generates ANSYS Full-Wave SPICE models for subsequent time- and frequency-domain analyses within ANSYS DesignerSI, ANSYS DesignerRF, ANSYS Simplorer or third-party SPICE-compatible circuit tools such as Synopsys HSPICE and Cadence PSpice. In addition, SIwave with ANSYS ALinks for EDA creates MCAD geometry for AMSYS HFSS, ANSYS Q3D Extractor, and ANSYS Workbench. Finally an engineer has the ability to choose which EM solver best fits his or her design requirements, since HFSS and Sentinel-PSI can be invoked from the SIwave user interface.
