To keep a good high-speed signal quality from driver to receiver on a PCB is not an easy task for designers. One of the most challenging issues is managing the propagation delay and relative time delay mismatches. Let me take you through the process...
What IC designers do to help us route high-speed PCBs
PCB designers typically have little or no experience with SPICE applications. No worries, follow along with me and get to know your SPICEs!
Zuken has been developing PCB design tools for the automotive market for years. With automotive electronics worth over $200 billion globally, and growing every day, Zuken is preparing for a brave new world of smart cars, and autonomous and electric vehicles.
I don’t think I’m generalizing when I say that designers working on complex high speed designs really don’t want to expend a lot of time and effort dealing with power integrity problems. And they especially don’t want to do it using tools that are detached from their design flow. In today’s complex PCBs, we’re talking advanced processors, complex FPGAs and superfast memories, which all share various voltage ranges.
DDR4, the fourth generation of DDR SDRAM technology, is the latest and greatest SDRAM standard and will continue to be until the fifth generation is released. The new standard features a point-to-point architecture that offers superior timing margins.
Last week I introduced you to the concept of S-Parameters, and now I’m going to explain a bit more about measuring them and simulating with S-Parameter models.
I’d like to explain to you in straightforward terms what S-Parameters are and why they’re so useful. When I say “straightforward”, I mean that in a technical sense, but this is a specialised area. If you’re not designing high-speed PCBs, or you don’t know much about signal integrity, you might want to tune out now.
