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.

Because standards adoption in this industry tends to be akin to turning around a battleship, what is often seen as new has generally already been in production for 10 years or more.

During SMTA Atlanta, I spoke with Albert Gaines of HiGain Design. We discussed Albert’s belief that everything starts with design and that too many engineers and designers focus solely on the final board at the expense of the documentation, which is a designer’s most important product. Do you consider your documentation to be a critical product?
