Routing DDR and high-speed bus interfaces can be one of the most daunting tasks in your design. Just getting all the various signal relationships and requirements defined and understood can feel like a PhD thesis on its own. With the new bus designer, all you need to do is simply describe the bus you are trying route and Constraint Manager for OrCAD will handle generating the appropriate constraints automatically.

Real-Time Impedance Analysis
Easily and quickly identify impedance discontinuity issues visually, without simulation models or extensive signal integrity expertise.
How To Maintain Connectivity in a Multiboard PCB System
Bringing a multiboard system together is a chance for the designer to spread their wings. As the circuit spreads, so do the risk of crossed signals. Some of the ways the circuits can...
Making the Little Things Count on Your PCB Design
Even as everything related to electronics shrinks in size, a few small areas that we have been able to ignore so far remain. Along with the physical reduction, we also encounter reductions in our...
The Next Generation of DDR5 Is Near: Here’s How to Prepare
This past summer, Cadence and Micron teamed up to demo the first IP interface in silicon for a preliminary version of the DDR5-4400 IMC. The chip was fabricated with TSMC’s 7nm...
Taking High Speed PCB Layout to the Next Level
The word from the boardroom is that high speed digital design begins to resemble RF work somewhere around the 1 GB/s. Anything that happens a thousand million times per second had better....
Techniques to Reduce EMI In Your PCB Designs
Electromagnetic interference (EMI) is electromagnetic energy that disrupts the signaling and it's all around us.
Lost in Transmission: Solving Common Issues in High-Speed Design
Creating a printed circuit board with high-speed design functionality is no small feat. The more complex a PCB design becomes, the higher the chances are of running into high-speed PCB design issues.
Mixed Signal PCB Design Techniques
The analog world in which we live is constantly being captured in one way or another, and the media is being shared globally. In between the creation and consumption of all of this data
Give me an L. Give me a T, Give me an E. What’s that spell? 4G!
The media darling of the season is the hot new 5G protocol. Of course, a large part of that ecosystem is vaporware or pre-5G demonstrations. We will be riding the 4G (LTE) wave at least for a while. I
Allegro Return Path Vision
Easily identify nets with inconsistencies between the signal and return paths and quickly find the cause in real-ime while you design without waiting for the SI engineer to perform analysis and...

Get help from the PCB design experts at EMA with the tips and tricks you need to achieve highspeed PCB design success.
Notes from the Board Room: on Signal Integrity
Signal Integrity is a make-or-break chunk of the design effort. Let's say that the last little bit of blue space on the board is right next to the RF receive chain. Let's further assume that at...
How Network Latency Affects the Future of Autonomous Vehicles
According to data from the Boston Consulting Group, the market for connected/autonomous vehicles (CAVs) will grow to 42 billion USD by 2025. It is also expected that by 2020, 10 million...
Notes from the Board Room - A day in the life of a Googler
In my quest to become a world famous PCB designer, (stop laughing!) I've taken to putting my own words on the screen and sharing them here. My job is to enable design wins, period. It's a cruel...
What is the Cost of Field Failures?
We see it in the news frequently; a battery explodes, car brakes malfunction, electronic systems are hacked, a material inexplicably fails. Field failures are costly and unforgiving, necessitating...
Remove unused sections of plated through holes in high-speed designs to improve signal integrity on your designs.
5 Ways to Assess PCB Constraint Management Systems for High-Speed Designs
A sound constraint management design process helps to foster a correct-by-design approach, reduces time-to-market, and ultimately optimizes the design process—eliminating the undefined,...
Notes on Impedance - Part 2
If one is good, then two should be even better. That's not really the principle behind differential pairs, but it's a place to start. Each line has resistance/impedance, so two of them would have...
Notes on Impedance - Part 1
There's scarcely a printed circuit board that doesn't have some form of impedance control. The trend is more and still more because the "Things" part of the Internet of Things all want to talk to...
