Dear Mr.Brooks
thanks for your this article.
And thank all experts for your comments.
I knew that self-coupling can be realized in Hyperlynx LineSim after proper
coupling setting.
But I'm not sure if self-coupling calculation is involved in Hyperlynx BoardSim.
At least, self-coupling can't be seen in Hyperlynx LineSim after exporting the
serpentine line from BoardSim to LineSim on my side.
Can any BoardSim users give me some clues to this topic?
Regards
Lei

I wrote an article once specifically on this effect. You can download it at

Also check out my latest book
"PCB Trace and Via Currents and Temperatures: The Complete Analysis"

Hi Lei:
HyperLynx supports self coupling ... (since 1999, in fact).
You need to make sure the crosstalk option/license is enabled, of course;
and make sure that the serpentine is in the same "coupling region."

Hi Lei,
I don't know about Hyperlynx, but ADS for instance has a separate coupling
controller which has to be used for traces in such cases. Maybe Hyperlynx
has something similar.

Resend
hi, experts
I want to see the time delay and signal quality impacted by serpentine line
patterns changed.
But it seems no changes found in Hyperlynx simulation results.
Can Hyperlynx support serpentine line self-crosstalk simulation?
if not, which tools support this simulation requirement?
thanks
BR
