Signal Net AnalyzerThe built-in signal net analyzer tool quickly and easily allows you to display quantities such as characteristic impedance (Z0) for both single-ended and differential nets. In addition, it provides the net length, propagation delay and reference layer for any selected nets. All possible paths (from each pin to every other pin on a net) are displayed and sorted in descending order of path distance; this includes extended nets. An example of an extended net is PCIe with an AC blocking capacitor. You can click on any individual path in the table so the variation in Z0 is graphically displayed and the selected path is highlighted in ANSYS SIwave's main layout window. Engineers can quick perform time domain transient circuit analyses with ANSYS DesignerSI or Synopsys HSPICE. The time domain analyses may include IBIS buffer models at both the driver and receiver ICs.
The signal net snalyzer produces 2-D MoM solutions for Transmission lines and vias that provide immediate feedback for propagation delay and characteristic impedance along with transient circuit analysis results. |
