Signal Integrity Advanced for very high-speed design
Builds on the functionality that the Signal Integrity option delivers and adds even more functionality.
Derive S-parameters for topologies that you have extracted and edited in Electrical Editor.
S-Parameters allow modeling passive interconnect behavior in frequency-domain (derived from measurement or like in eCADSTAR by simulation). S-Parameter export from the Electrical editor handles modeling of passive circuit elements only.
S-Parameters describe coupling and transmission behavior of a system for a wide frequency range. Issues at high frequencies which for example may cause crosstalk can be identified, quickly.
You can use exported S-Parameter models in external applications that support it and mix them with other kinds of models.
TDR (time-domain-reflectometry) analysis sends a fast pulse down the PCB trace and displays the returning reflections, which indicate changes in impedance. This allows estimating signal integrity performance without the need to have IBIS buffer models assigned.
