Home Education Center HS Memory Interfaces

This workshop is aimed at developers who want to implement high-speed memory interfaces on custom boards. Memory interfaces are used very often, they will be faster and faster – and the design issues are more and more challenging. This Workshop is designed for developers who not only design schematics but also design systems and the layout.

You will learn the memory device specifics relevant for logical and physical design. Timing and voltage margins will be discussed.

You will learn to use signal integrity simulation to optimize high-speed memory interfaces. IBIS models and simulation are used to explain the effects and potential bottlenecks. You will learn how to implement high-speed memory interfaces, including board level design topics.  Furthermore, the power supply issues will be discussed. Finally, you will learn board level verification options.
