Zynq design from scratch. Part 1.
Almost a year ago I received a parcel by post from US. When I opened the parcel I found this box.
The ZedBoard was a present from someone involved in promoting the new Zynq device from Xilinx, but with no strings attached. At that time I was busy working as an ASIC designer and had no time to play with the board. It wasn't until December in 2013 that I had a chance to unpack the box and power-up the ZedBoard.
At that time I got an email from Per and Andreas at Silica (Avnet) here in Stockholm, where they offered a one day hands-on training class on the Zynq-7000 using the ZedBoard, part of the "Xilinx Speedway Design Workshops". Here is what this workshop covered:
Introduction to the Zynq-7000 in Vivado AP SoC
"This class demonstrates the techniques and tools used to create a basic Zynq-7000 AP SoC design. Through a series of instructor presentations and hands-on labs, hardware and firmware developers will learn the required steps for creating a complete Zynq-7000 AP SoC design on ZedBoard. The Zynq-7000 AP SoC architecture is explained, including the ARM® Cortex™-A9 processing system (PS) and the 7 series programmable logic (PL). The course also details the individual components that comprise the PS such as I/O peripherals, clocking, interrupt, AXI interfaces and memory controllers. Emphasis will be placed on efficient PL-to-PS interfacing including processing interrupts generated from a PL peripheral. To complete the design flow, the critical steps of hardware and software debugging techniques will be shown".
This training session was the head start I needed. I went home and started to play with my ZedBoard. At the same time a decided to write this blog and here we are. All of you who have read my "FPGA design from scratch" blog will feel at home. I will follow the same idea and describe the whole design flow in an easy to understand fashion.

Learning by doing
Aristotle once said, "For the things we have to learn before we can do them, we learn by doing them". So true. Let's practice some learning by doing.
Not reinventing the wheel
We will use a lot of material already available from Xilinx, Avnet and other companies. We will try to find solutions to our problems by searching on internet.
An interactive meeting place
A would like the blog to be interactive and not a one-way document. I invite all of you, newbies to professionals to ask questions, make comments and suggestions for subjects you are missing.
It wouldn't make sense writing a tutorial like this and not using Avnet's and Xilinx's in-depth knowledge about their products found in their web pages, user guides and other documents. I would like to thank Avnet and Xilinx for allowing me to use images and text from their documents and to link to their web pages.
Here is a link to the Xilinx documentation library.
Xilinx provides recorded E-Learning for courses at our convenience. They are available at no charge.
There are several forums discussing FPGA design. The Xilinx forum is one of them. The Avnet forum and ZedBoard forum are two others.
Subscribe for FREE to the new Xcell Journal Digital. Here are links to old XCell magazines.
There are a number of dedicated search engines, searching for FPGA information. FPGASeek is one ChipHit is another.
Support, Answers Database
You may find an answer to your question in the Xilinx support page.
Xilinx provides targeted, high-quality education services designed by experts in programmable logic design, and delivered by Xilinx-qualified trainers. They offer instructor-led classes (both in person and online) and recorded e-learning for self-paced training. Some courses are completely free! Doulos is running a 3 days course called "ARM Cortex-A9 for Zynq System Design".
To post a question to Xilinx you should use WebCase.
The goal of the Xilinx Wiki site is to provide technical information and collaborate with the community on Open Source projects that are being done in Xilinx. Xilinx also provides a Git repository to help with open source development and collaboration, and all sources can be downloaded from the GIT repositoryXcell Daily Blog
Here is Xilinx own blog, Xcell Daily Blog.
Xilinx University Program
The Xilinx University Program (XUP) includes academics from top-tiered universities across the world. XUP provides top-quality teaching materials that are easily accessible to professors to incorporate into their curriculum. XUP offers workshops to professors and academic staff at no cost. These workshops are conducted by Xilinx as well as application area experts, providing in-depth practical and theoretical aspect of FPGA technology.
What to expect from this blog
You are welcome to follow my blog. I hope it will give you a head start in using the Zynq-7000 All Programmable SoC. Here is what I plan to do first.
- Select a computer to use. In my case a MacBook Air
- Setup a virtual machine using VirtualBox.
- Install Ubuntu Linux 13.10 64bit in the virtual machine
- Install Xilinx Vivado Design Suite (the Linux version)
- Use the Vivado software to generate a configuration bitstream
- Use Vivado SDK to write a simple program
- Connect the ZedBoard to the computer
- Configure the Zynq FPGA part and load the program
- Run the program that will light up some LEDs on the board
Just one last thing
We are going to have fun.
