Via modeling - what do I really need?

Posted Nov 2, 2011, by Patrick Carrier

The whole via simulation issue is admittedly complicated, and I think really boils down to whether the vias are single-ended or differential, and at what speeds you are running. When the vias are differential, the return current is basically self-contained around the vias since they have equal but opposite signals on them. Because of this, the built-in analytical model in HyperLynx models differential … 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
