Is it SSN or is it Crosstalk?

Posted May 2, 2012, by Patrick Carrier

In the lab, both simultaneous switching noise (SSN) and crosstalk look the same.  They appear as unwanted pulses of energy that line up with the (aggressor) signal edges.  However, the mode of energy coupling is much different between SSN and crosstalk.  In the case of crosstalk, they are lining up with the edges because the signal edges are coupling energy onto the victim signal through electric (and … Read More

Crosstalk is everywhere

Posted May 1, 2012, by Patrick Carrier

Crosstalk is everywhere.  Really, in a more general sense, noise coupling is everywhere.  Usually the method of noise coupling is traditional “crosstalk” – the unwanted transfer of noise from one place to another through coupled electric fields.  This most often occurs on PCB designs with dense routing, and on wide parallel busses.  Even on newer SERDES busses, however, it is still … Read More

HyperLynx 8.1 Released

Posted Jul 21, 2010, by Steve McKinney

Last week we released the official version of HyperLynx 8.1. If you've been a beta tester (I know there are a lot of you out there), make sure you go to SupportNet and get this latest release! This release includes new technology in both HyperLynx SI and PI.  Some key things in the release worth taking a look at if you haven't been beta testing: Tons of new capabilities in HyperLynx PI but … Read More

What's your excuse?

Posted Dec 16, 2009, by Steve McKinney

Over the last few months, I’ve visited dozens of customers talking with them about power distribution design.  Power Distribution design on the PCB is one of those areas that is fairly new to many companies, so there is a minimal amount of in-house expertise.  Usually there are one or two people that are the go-to guys/gals for solving a power problem but on the whole, power distribution design (and … Read More
