Exploring What’s New in CR-8000 2020
What drives the features that are added or updated in a new release? The majority of the changes or additions in any Zuken tool release are customer-driven. Our customers provide valuable insight into emerging technologies, process and methodology changes, and the direction in which their EDA needs are taking them. This post focuses on the high points of the CR-8000 2020 release.

How to Calculate Trace Length from Time Delay Value for High-speed Signals
To keep a good high-speed signal quality from driver to receiver on a PCB is not an easy task for designers. One of the most challenging issues is managing the propagation delay and relative time delay mismatches. Let me take you through the process...

Inside Signal Integrity: Impedance Control - Part 2
In part 1 of this blog we took a back-to-basics approach and discussed line impedance and its effects in signal integrity. As every electrical conductor comprises capacitance, an inductance, and a frequency-dependent ohmic resistance, and with increasing frequencies, these electrical characteristics will influence and distort the signal.

Inside Signal Integrity: Impedance Control - Part 1
Impedance and impedance control belong to the oldest and most often discussed topics in PCB design. They are especially important with the high-speed design when related to signal integrity. In this, the first of a two-part blog, we’ll go back to the basics of impedance/impedance control and consider what influences line impedance. In part two, we’ll set about controlling it.

What You Really Need to Know When You're Routing PCB Differential Pairs
Tips for when routing differential pairs - You can tell when something isn’t as clear as it should be. The same questions come up time and again. You ask three experts and get three different answers. Routing differential pairs can be like that. Why? Because “it depends” - on exactly what signals those pairs are carrying and what kind of PCB you’re creating.

Faster Board Speeds Demand Constraint-driven Design
Do you still use Post-it Notes? Invented in 1979, this simple, yet incredibly powerful, communication mechanism is still commonly found in engineering and design departments. Despite modern electronic communication, many companies still struggle to provide a replacement for their ease-of-use and versatility.

25 Years of High Speed Design – Looking Back to the Future
It’s 25 years since the first FED Conference took place in Berlin back in 1993, as a gathering for the German-speaking electronic and PCB-related industry. This also happened to be the year we consider as the birth of high-speed design.

A Few Thoughts on Avoiding DDR4 Layout Problems
DDR4, the fourth generation of DDR SDRAM technology, is the latest and greatest SDRAM standard and will continue to be until the fifth generation is released. The new standard features a point-to-point architecture that offers superior timing margins.

Using Vias to Maintain PCB Signal Integrity Featuring High-Speeds in a 3D Environment
This is the second in my series of blog posts looking at the challenge of maintaining PCB signal integrity with now-common ultra-high speeds and growing adoption of PCB design environments to design in true 3-D. Today I focus on vias and the use of return vias to overcome the issues highlighted in Part 1.

Defining and Routing PCB Constraints for DDR3 Memory Circuits: How-to Movies
As Zuken technology partners, we are often asked about how best to set PCB constraints for double-data-rate (DDR) memory, and how to route to those constraints. This question arose recently when we were asked to create a common style of DDR3 design for training, and we tried mining the web for detailed information on PCB constraints. There had to be something out there, we thought.
