    - Introduction
      Signal integrity (SI) is a measure of the quality of an electrical signal.
    - Setup Methods
      The PollEx SI Explorer is a pre-layout simulation tool. It can be used for experimenting with various topology options to find routing constraints for critical nets.
    - Start from Scratch
      For easy building up the practical complex topologies, this feature allows you to study versatile net topologies depending on signaling types, for example: Single-ended, Differential, and Multi-coupled using built-in topology model libraries.

Network Analysis Parameters

Control the frequency-domain analysis for extracting network parameters such as S, Y, and Z parameters.

The parameters include the starting and ending frequencies, frequency sweep type (decade or linear), and number of frequency points. The network parameters are calculated at the you-defined number of frequency points when linear frequency sweep is employed. However, when decade frequency sweep is employed, the number of frequency points is assigned to each decade within the frequency range.

Starting/Ending frequency (MHz): Denotes the starting and ending frequencies during the network parameters extraction.
Frequency sweep type: Specifies the type of frequency variation. Linear or decade should be one of them.
Number of frequency points for sweep type: Denotes the number of observing points of frequency between starting and ending frequencies.

You export the current constraints as file (*.ecns) in current design folder which could be used by import function.
