Xilinx Zynq 7000 Sample Request

(1/4) > >>

diyaudio:
I'm looking at doing a another diy project project next year, I always had my eye on the Xilinx Zynq 7000 series, however I'm curious do Xilinx  even sample them ?

julianhigginson:
I'm not aware of them sampling much, beyond brand new silicon to huge customers.... but if you have a relationship with your distributor,  wouldn't hurt to ask...

of course, there are all bga parts that will need a DDR3 RAM layout to actually live up to the whole point of having them...  so to evaluate the use of a zynq in pretty much any design it would be faster and cheaper to find an appropriate zynq eval board, that has the connectivity to add whatever other custom things you want, and prototype from there....

ebclr:
No they don't sample, for simple mortals only fortune 500 can do this, i already have tried without success, they want to sell it, and is more expensive than boards with the zinc on board, the easiest way to have a Zinc is buying a Parallella Board

I agree, it's definitely a non-trivial exercise to get a Zynq running.

Much as it leaves a lot to be desired as a test instrument and mid-level deveopment, the Red Pitaya is the least worst option I've encountered in terms of a reasonable cost development and proof of concept platform for the Zynq. The hardware is reasonably sound, it's just the nonsense around the documentation, much of which is out of date, and the way they try to monetize it by selling half baked apps.

Remember that this is an application processor plus FPGA, so typically you'll probably choose to get Linux running on it, which in itself is a significant project if doing it from scratch. For the project I used it on, we use Red Pitaya boards directly with our own hardware (frequency agile RF quadrature up and down converters). It's very low volume so we'd be nuts to spend months getting our own board working.

Another board I tried was the Zybo, which has a tutorial book http://www.zynqbook.com/downloads/The_Zynq_Book_Tutorials_Aug_15.pdf but I found it was geared towards ticking a few course boxes for students rather than getting you to a position where you could realistically do something with it on your own.

julianhigginson:
there's more and more zynq options now. the trick is you probably want a 7020 unless your FPGA fabric needs are really low... so that cuts out all the cheapest zynq board options for a general play about platform....

One good low cost solution, depending on your io needs is the new pynq board (released yet?) from digilent. which is an arduino format thing with a pretty good 7020 part. basically it's their older arty board but upgraded to a zynq from the original artix7 part.

there's a crowd funded zynq som that just had disaster after disaster but stool might come through... snickerdoodle. looks good if they can ever make it.

there's also a Chinese option that's available to get now, and seems pretty solid (my friend is using it) it's in a raspberry pi format, but has two reasonably high density connectors at the bottom for plugging into a board of your own design with whatever you need attached. they also sell a more generic som that you can use.... I'm on my phone, so can't get the links right now but will try to do that later.
