It’s a deceptively simple question. On a simple schematic design, a net’s connections can be easily traced using the Navigator assistant in Virtuoso® Schematic Editor L. With larger designs it gets trickier. In an ideal world you would use SKILL, but if the design includes bus/bundles, iterated instances, view switching, and especially if there are configurations, this is near impossible.
Fortunately, there is a non-SKILL solution. You can find all of a net’s connections using the Virtuoso Schematic Editor L Probes assistant.
The Probes assistant is a dockable assistant where you can view the probed nets across a design hierarchy. You can identify connections that exist for a net, filter these connections to focus on those of most interest, and save the probe path information to a CSV file.
The Probes assistant has been around for a while, but if you haven’t had the chance to use this assistant or you just didn’t know what to use it for, do watch the Identifying Net Connections video available on Cadence Online Support.
