Solving LPDDR4 Technology Design Challenges

The ongoing trend to lower power applications across all industry segments (driven by mobile devices, but now being used in wider industry segments like automotive and industrial automation) has created new design challenges for PCB designers.

Governed by the framework of the JEDEC standard JESD209-4C, the relevant rules and constraints for LPDDR4 memory devices and their usage have been adopted by all semiconductor vendors. The tight timing and voltage margins require a holistic design approach combining high-speed constraining and integrated analysis steps ensuring the various design rules.

In this presentation you will be introduced to the necessary steps in constraining and validation of LPDDR4 on the basis of a real design realized in CR-8000 Design Force right first time.
