Practical Modeling of High Speed Channels Based on Datasheet Input

As Dave Dunham from Molex Corp. likes to say “When designing high speed serial links beyond 10 GB/s, everything matters“.  Part of that everything is accurate modeling of transmission line losses. It is important to model dielectric and conductor loss accurately.

Here is a very useful presentation with speaker notes on the topic of “Practical Modeling of High Speed Channels Based on Datasheet Input” presented by Bert Simonovich, Lamsim Enterprise Inc at EDICON 2017.

Here is the motivation of the methodology proposed:

As my friend Eric Bogatin often likes to say, Sometimes an OK answer NOW! is better than a good answer late.” As a high-speed signal integrity practitioner and backplane architect, I often have to come up with an answer sooner, rather than later because of the impact to time and cost to my clients. And that’s why I have been motivated over the last few years to research and develop a simple methodology to accurately determine parameters to feed into modern EDA tools .

Happy Designing…..!!!

Webinar: Solve your Signal & Power Challenges using SIPro & PIPro

I will be conducting this Webinar on 6th April at 11.00am – 12.30pm (IST). Look forward for your participation.

Keysight Technologies is offering free webinar on 6th April 2017, specifically designed for Signal and Power Integrity Engineers trying to accurately model their printed circuit boards (PCBs), a task that is now more challenging given today’s ever increasing data rates. During the webinar, attendees will learn about SIPro (Signal Integrity Professional) and PIPro (Power Integrity Professional) tools from Keysight Technologies.

SIPro and PIPro provide a cohesive workflow within ADS for signal integrity and power integrity applications in high speed digital board design. Specific use cases will be demonstrated, which will reveal the powerful capabilities of SIPro & PIPro.

Topics to be covered:

– Challenges of increasing speeds & complexity

– Why you need a Channel Simulator

– S Parameters for frequency and time domain data mining

– EM simulation for Signal integrity

– Fast parallel bus DDR4 simulations

– How to Analyze 100 GbE – KP PAM4 vs NRZ

– Power Integrity basics

– Power Integrity IR Drop
