Extracting coupled nets to SigXP

archive

I would like to be able to extract a victim net and two or four adjacent aggressors from PCB SI to SigXP to perform some detailed "what if" crosstalk experiments.  I know that I can build coupled topologies in SigXP, but to attempt to duplicate the net structure from PCB SI in SigXP would be incredibly time consuming.  At some point there was an app note that talked about using Specctraquest to create black box models for coupled nets, but I cannot seem to find it.

Does anybody have any suggestions or comments?

I am using PCB SI 610 15.7.

  • Found it under Articles->Modeling.  Here's the description:

    Describes a method for creating a black box model (DML) for three coupled differential pair. Using signal probe within Allegro PCB SI makes it possible to extract single-ended nets and differential nets into Sig-Xp. This document describes a method for creating a black box model (DML) for three differential pairs that are coupled to one another. This black box model can then be placed and used within Sig-Xp just as any other component. The same basic method used for this particular example could be used to create a black box model for any arbitrarily routed interconnect.
