Course Description

This course teaches hardware designers who are new to high-speed memory I/O to design a memory interface in Xilinx FPGAs.

The emphasis is on:

• Introducing the basic concepts of high-speed memory I/O design, implementation, and debug using Xilinx 7 series FPGAs.
• Learning about the tools available for high-speed memory interface design, debug, and implementation of high-speed memory interfaces.

The major memory types covered are DDR2 and DDR3. The following memory types are covered on demand: RLDRAMII, LPDDR2, and QDRII+. Labs are available for DDR3 on the Kintex®-7 FPGA KC705 board.

* This course focuses on the 7 series architecture. Check with your local Authorized Training Provider for the specifics of the in-class lab board or other customizations.

After completing this comprehensive training, you will have the necessary skills to:

• Identify the FPGA resources required for memory interfaces
• Describe different types of memories
• Utilize Xilinx tools to generate memory interface designs
• Simulate memory interfaces with the Xilinx Vivado simulator
• Implement memory interfaces
• Identify the board design options for the realization of memory interfaces
• Test and debug your memory interface design
• Run basic memory interface signal integrity simulations
