Mentor Paper: Using HyperLynx DDR Wizard for QDR-IV


Reading time ( words)

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.

Decoupling Capacitors’ Impact on Power and Signal Integrity

09/03/2019 | Chang Fei Yee, Keysight Technologies
It is crucial for hardware designers to identify the resonant frequency of each element of the PDN on a PCB and its impact on power integrity. A PCB with poor power integrity—such as a higher-than-targeted PDN impedance across the wideband range—results in SSN and a shrunken eye diagram of the signal transmitted by the IC that draws power from the PDN. This article demonstrates the post-layout co-simulation of power and signal integrity.
