Creating hardware based off of ZedBoard, which portions of the ZedBoard schematic do I need?

I need a few things. I will reference pages from the ZedBoard Rev D.2 schematic.

One, I the programming interface to the SoC via USB. I believe that this is covered on page 12.
I also need the ability to interface with an SD card, which is contained on page 6 and page 10 (MIO bank).
I need an XADC channel, which is covered on page 2 (connector on the bottom left) and 8.
I need basic UART (not via USB), so I believe I just need some MIO pins (sheet 10).

Apart from that, I believe that the FPGA power on sheet 11 is necessary. In addition, to generate all of the different DC voltages, I believe that the power regulation shown on sheets 15-17 are necessary.

Are there any other components from the schematic that I need to create working hardware? There are so many signals that go to and from each sheet of the schematic, it can be a little hard to follow and discern which ones are needed to create working hardware based on the ZedBoard. Thanks for the help.

Hi Michael,

Please take a look at the developing zynq hardware speedway located here. http://zedboard.org/support/trainings-and-videos
It shows the basics of hardware platform design.

Hi Josh, thanks for the reference. I guess before I get started looking through the lectures, since the ZedBoard has all of the modules that I need, would it be possible just to refer to the ZedBoard while creating the hardware schematic?

Also, I have a question that you may or may not be able to answer -- does using the XADC require any external JTAG connections? For example, the connections shown from the Xilinx JTAG Header on sheet 8 of the ZedBoard Rev D.2 schematic.

Hi Mike,

I am confused by your first question. Can you please elaborate?

As far as using the XADC and needing a JTAG connection goes. It depends on how you want to connect to your Zedboard. You can do all your development via an SD Card if you want. However most go with the JTAG boot development to avoid having to create boot.bin files over and over.

The Speedways I referred you too go through both methods at some point.

Hi Josh,

Sorry about being unclear! I guess to be more specific, my question revolves around the content of the Speedways. I haven't had time to go through them yet, but what sorts of things do they cover? At the moment, I'm trying to create a schematic for my own hardware, so I'm directly pulling various modules from the ZedBoard schematic to use in my board. I was wondering if the Speedways would be directly helpful to me during this phase of my hardware development.

Hi Michael,

The Speedways cover the development flow using Vivado and SDK. If your strictly interested in designing your own schematic, it would be beneficial to go through the hardware course so you understand what is typically required for a Zynq design. The Hardware Speedway goes through configuring DDR and various Zynq Peripherals. I am not saying you have to, but I certaintly would help especially if your new to the Xilinx Zynq SoC.
