Hi,
This is a conversation that I've recently had with one of the attendees to the RVfpga WS that we held at Alicante last September. Find below our conversation, translated using DeepL from Spanish to English.

Hi Daniel,
I'm one of the attendees of the RISCV course of Imagination Technologies that was given at the last Sarteco conference. I have a student who is interested in these topics and I would like to try a project with him, for which I would like to get an FPGA like the ones from the course, which if I'm not mistaken was a Nexis A7 (*). I've been looking for it and I've seen that it is out of stock in many places, and where I have found it it costs about 400 €.
Do you know if there is any way to get it cheaper, taking into account that it is for teaching?
Best regards and thank you very much for your attention,
Ricardo.
(*) Which I understand to be the same as the Nexis A7 T.
我是上届 Sarteco 会议上 Imagination Technologies RISCV 课程的参加者之一。 我有一个学生对这些主题感兴趣,我想和他一起尝试一个项目,为此我想获得一个像课程中的那样的 FPGA,如果我没记错的话,它是 Nexis A7 (* )。 我一直在找它,发现很多地方都缺货了,在我找到的地方售价约为 400 欧元。
考虑到它是用于教学,您知道是否有任何方法可以更便宜?
谨致问候并非常感谢您的关注,
里卡多.
(*) 我认为与 Nexis A7 T 相同。
Hi Ricardo:
Yes, in the course we use a Nexys A7, which is electronically the same as the previous version called Nexys 4 DDR. Both have a Xilinx Artix7 FPGA. You need the Nexys A7-110T which has the larger FPGA.
It's been a while since I've looked up board prices. I know there was an academic price which used to be closer to $200, but I am not close to this topic, so I asked Robert Owen for advice. He maintains the relationships with our project partners.
I can add that next year we will have a version of RVfpga that runs on the lower-cost Digilent Basys 3 board. We are working on this at the moment.
Dani
Dear Ricardo
The board is the Nexys A7-100T and the Digilent part number is: SKU 410-292
(1) Supply
There have been global shortages of semiconductors and this has affected many things, including development boards.
We know from discussions last week (14th Oct'22) that new supplies are coming through to distributors by mid-December.
As of October 22nd, Digi-Key, Mouser and element14 are all showing stock.
https://www.digikey.co.uk/en/products/detail/digilent,-inc./410-292/5117190
(2) Academic Pricing:
Digilent offer a special Academic Price to eligible institutions of $262. A discount of 25% on the regular $349 price.
Follow their Academic verification here: https://digilent.com/shop/academic/
410-292 | Nexys A7-100T (previously known as Nexys 4 DDR) | $349.00 | 25% | $261.75 |
(3) Donations
The Xilinx University Program ("XUP") support universities all around the world with boards.
You can ask them for support here: https://www.xilinx.com/support/university/donation-program.html
Remember - they will be looking for ongoing use of donated equipment in labs and student & research projects, not just one-offs.
Hope this helps!
Robert Owen
