Lee Ritchey is now confirmed

April 29, 2012 by Rolf Ostergaard

I am happy to announce that the two courses with Lee Ritchey are now confirmed. We have enough participants in both Oslo (20-22/6) and Copenhagen (25/6) to run both courses.

That means you should make arrangements for travel and accommodation to get the best prices and availability. I have added an alternative hotel in Oslo on the webpage under accommodation, but make sure you check your own company’s hotel deals and policies.

If you need hotel for Copenhagen, please note that the Hilton where the course is held, is right in the airport. And the public transport to the city center is fast and cheap, so your options are plenty.

We still have open seats on both courses, so please send your co-workers a note to get them on the same page as you will be this summer. Nothing worse than coming back from a great course with the understanding that some design practices have to change – and then having to explain it all over to your co-workers. Get them to go as well – now 🙂

Thanks – looking forward to see you.

Why autorouting a PCB doesn’t work?

February 14, 2012 by Rolf Ostergaard

Why don’t you use autorouting? No-one sane would hand route the internals of an ASIC. No-one sane would hand route the internals of an FPGA. Why are we constantly hand routing PC boards? During my recent visit to DesignCon in Santa Clara, CA, I took the time to research this topic a bit. I went… Read more

Stack-up Design Course

February 6, 2012 by Rolf Ostergaard

We have a brand new course on stack-up design coming to Copenhagen on June 25th. Right in the airport, so it’s easy to fly in and out the same day. Just walk to the Hilton from your flight (or train). With increased signalling speed, engineers are facing increased difficulties meeting signal quality requirements. This puts… Read more

Lee Ritchey in Oslo, 2012

February 5, 2012 by Rolf Ostergaard

Lee Ritchey is one of the industry legends on high speed design. I worked with Lee back 12 years ago at 3Com in Silicon Valley and have since had the pleasure of arranging a number of 3-day signal integrity courses with Lee in Denmark, Sweden and Norway. The next training course we do with Lee… Read more

Transmission line loss calculator

February 5, 2012 by Rolf Ostergaard

AWR has one of the nicer free transmission line loss calculator apps I have seen in a long time. Highly recommended. Recently I needed to approximate a cable with the following insertion loss for a 25 cm long strip: The approximation was required for an IBIS simulation in SigExplorer, so a microstrip model would be… Read more

Lee Ritchey in Oslo, June 20-23, 2012

February 5, 2012 by Rolf Ostergaard

3 Fantastic Days with Signal Integrity. Most modern electronics operates with digital signal switching times measured in the 100-300 ps range. At that rate the switching causes reflections on any trace longer than a few cm. The frequency content of the signals run into the GHz range. Parallel traces of just a few cm can… Read more

Video: Easy PDN Measurement

February 5, 2012 by Rolf Ostergaard

A quick how-to for you: the PDN measurement video. How do you do validate bypass capacitor selection and effectiveness on the mounted PC board? This is very easy to do, and this video was created to illustrate how this is done in the lab with a Rohde & Schwarz network analyzer. It used to be… Read more

Good PDN: Low Impedance to infinite frequency?

January 15, 2012 by Rolf Ostergaard

Signal integrity experts have taught us to design power distribution systems that can support all devices on the board with a low low impedance up to a high “target PDN frequency”. We all know, trust or believe that is important. But we soon realize that achieving low impedance from DC to infinity is impossible. So… Read more
