To take full advantage of the AWESOME SAUCE that is Zynq, you will need the Xilinx software and tool chain. To get it go here:
At the time of writing this entree, Xilinx is on version 2012.2 - 14.2. Go ahead and download the appropreate installer for the platform you are running on. The software is very similar across platforms short of some visual things. I will be writing this how-to for Windows-7 - so I will be downloading the 6.2GB .tgz file.
Ok, first go to the download link above and select your appropriated download. You will notice that Xilinx would like you to login. I know, I know ... don't worry. A login allows you access to their forums which is defiantly an amazing resource. If you don't have a login, create one and then sign in. Confirm some information about yourself and download the tools. Assuming you aren't on a Google Internet Connection, it's going to take a bit of time to download it. It's ok, I'll wait.
Ok, I lied, I'm not waiting.
Once you have the archive downloaded, you will need to extract it and install it. Note this is going to take a LOT of HD space. But, with Newegg selling 1.5TB drives for less than $100 I'm sure you'll be fine :D
Once you have everything installed, you are going to be presented with the Licensing Manager, it looks like this:
Select "Get Free ISE WebPack License" from the radio buttons and hit Next. A little window will pop up after a second or two and it will have some information about your machine in it. Click "Connect Now" to open your browser and go to the licensing webpage.
It will ask you to login and confirm some information. After hitting Next, you will see the license manager. It looks like this:
That's it! Stay tuned for my first Zynq Xilinx project using PlanAhead, EDK, and SDK!
