Hi,

Any suggestions on how to model specific oscilloscope probes in Boardsim? I am trying to get as accurate simulation results as possible, to match measured scope traces.

Does the built-in oscilloscope model the probes and what values does it use? (10pf, 5pf probe etc)

I know there is a probe.mod model library but I am not sure how to apply this?

Cheers

Robert

Spice is appricate for probe mdeling. You may need to look for the model from oscilloscope venders. Tek have a paper about the probe modeling for signal fidelity http://www.tek.com/technical-brief/tekconnect-probes-signal-fidelity-issues-and-modeling.

For accurate result, the key is the driver/recerver model, or via modeling if GHz bit rates. It seems no worthful to put effors on the probe modeling except you are reasching how to design a probe with high signal fidelity.
