Practical DDR3 - Part 2



In part 1 of our DDR3 webinar, we established some of the key points to consider when handling the timing issues of DDR3. In part 2, we will introduce the following copper-related aspects of DDR3:

  • Serpentines
            - Why they are needed
            - When to use them
            - Proper methods
            - Issue that occur when not done correctly

  • Signal Group and swapping
  • Pin delays and swapping
  • On-Die-Termination (ODT)
            - What is it
            - Why it is important

  • Vias

We will demonstrate these concepts and address rules, schematic issues, length matching, and xSignals in Altium Designer. Please note that many of these concepts apply to other EDA tools.
