Mentor Paper: Using HyperLynx DDR Wizard for QDR-IV
June 10, 2015 | Mentor GraphicsEstimated reading time: Less than a minute
The quad data rate IV (QDR-IV) memory interface protocol is used for reduced-latency applications. It features two independent bi-directional data channels, each running at double data rate (DDR).
Mentor Graphics’ newest white paper walks PCB designers through several ways to capitalize on the benefits of the DDRx Wizard batch simulation to validate the QDR-IV bus. This PDF is available for download by clicking here.

Breaking Down Barriers: The Connectivity of Machines in SMT Production Lines
05/14/2025 | Bill Cardoso, Creative ElectronAs the world increasingly moves toward erecting trade barriers, we find ourselves in a paradox. Across the globe, the rise in tariffs and protectionist policies is creating a more fragmented global economy, with nations seeking to insulate themselves from external economic pressures. However, within the confines of the SMT production line, the trend is moving in precisely the opposite direction—toward greater connectivity, integration, and collaboration. Rather than isolating one machine from another, SMT production lines are increasingly interconnected, with data being shared across various stages of the process to improve quality, efficiency, and defect detection.
Elementary, Mr. Watson: Design Data Packages—Circle of Concern or Circle of Influence?
05/14/2025 | John Watson -- Column: Elementary, Mr. WatsonI've often been asked, "Can you have a perfect PCB design?" At first blush, it seems like the answer should be yes. After all, if you follow all the rules, double-check your work, and use the right tools, it should be perfect. Right?
The Shaughnessy Report: Solving the Data Package Puzzle
05/12/2025 | Andy Shaughnessy -- Column: The Shaughnessy ReportIf you ask fabricators about their biggest challenges, they’ll often point at PCB designers—the readers of this magazine. Yes, you! Why is it so difficult to create the ideal data package? It’s a fairly straightforward task. But this part of the design process keeps tripping up designers, even those who started in the industry before Pink Floyd split up.
