content: It looks like Xilinx has decided to introduce something that common folks can actually use and play around with:https://www.xilinx.com/news/media-kits/xilinx-expands-into-new-applications-with-cost-optimized-ultrascale-portfolio.htmlThere is a presentation PDF which is worth going over if you're interested.I wonder what they are going to cost. For Zynq, since cheapest existing Zynq ZU2 goes for US$270, ZU1 has got to be cheaper than that, which kind of goes into regular Zynq-020 pricing territory. So seeing how ZU1 is not that much smaller than ZU2, I would expect high-100 to low-200 US$ for ZU2.But I'm personally much more excited for new Artix US+ devices, as they have a potential to offer a great platform for interfacing with DAC/ADC via JESD204B interface, which often go into 16Gbps territory, as well as PCI Express 4.0 support, and NATIVE support for MIPI and LVDS for up to 2500 Mbps per pin pair, as well as my personal favorite - support for DDR4-2400! It it not explicitly mentioned in the press release (or I missed it) if these devices are going to be available in free Webpack license, but if their history is anything to go by, they include their entire "Cost-optimized" (as they call it) portfolio in that free package. And - again, the question of price. Right now the cheapest Kintex US+ is over US$1100 on DK, so there is a big hole in the segment and they will likely eventually introduce enough devices to fill entire 200-1000 market segment. So if I were to guess, I'd say between US$100 and 200 for the smallest density on Digikey. It's cool that they now offering a single package 676 balls@1mm pitch with a vertical scalability across entire family, with full 16.3Gbps transceivers.What do you guys think?

content: The UltraZed is $485 with a ZU3, so I can't imagine a ZU1 will make Zynq Ultrascale+ all that much cheaper of a platform... Fun stuff though.Artix US+ is indeed more interesting. Xilinx has gotten better at reducing the announcement to availability delay in recent years, so maybe they'll hit Digi-Key by Christmas?

content: Quote from: miken on March 17, 2021, 09:13:08 pmI hope so. I would be up for a samples, but I doubt Xilinx is going to be interested unless I wave a 1M$ purchase order over them, so DK it is. Also I hope they will add smaller 1 mm pitch packages in the future as the only one announced so far is 676 balls. That said, I will reserve my judgment until I can see pinout diagrams, because some 676 pinouts are worse than others, Artix-7 ones being among the worst as it requires a 10 layer PCB (or expensive blind vias) to fully route out, while 676 package for Kintex devices is much better can be easily fully routed out on a 6 or 8 layer boards with no BB vias required.

content: Quote from: NorthGuy on March 18, 2021, 03:02:59 amThat is actually not surprising because transceivers take a lot of pins (they require ground "fence" around them for SI reasons). Take a look at existing Kintex US+ device diagram in FFVB676 package - you will see it clearly.More important issue is that there are not that many 3.3 V-tolerant pins, as majority of IO are HP and so 1.8 V max.

Here you can take a look before I get my hands on this new puppy! I will share the results when I made progress.It has 2 SFP, 2 Gigabit Ethernet, 2 USB host, 64Bit DDR3, one SATA, one 4K HMDI, one audio codec, and one LCD, and a lot of expansion connectors including 2.54mm and FPC's with 10Gbps SERDES for External ADC and DAC

So, it is long long wait until you can buy Artix-U in China. I think it's at least a year until you can buy Artix-U anywhere.I hope prices won't be too high, and if so, this may even pull prices for 7-series FPGA down because they're getting obsolete with DDR3 and PCIe2. That's my own version of wishful thinking

content: Quote from: NorthGuy on March 19, 2021, 03:37:12 pmYea that's what I think too. Which kind of sucks as I'm really looking forward to playing around with them.Quote from: NorthGuy on March 19, 2021, 03:37:12 pmHistorically prices for 7 series are undercutting S6 devices to encourage migration, so I think it will be the same with newer AU. The smallest AU has resources similar to the A100T, so I suspect it's going to be priced at the same level, which is US$100-150 on DK depending on a package and speed/temp grade. I doubt there will ever be 20$ AU devices which will compete with lower-end Artix, but I think we will eventually get smaller ones than AU10P - just like we got new A12T/A25T die some years since original introduction.

content: Quote from: SiliconWizard on March 19, 2021, 09:52:20 pmOK, this is really interesting. What kind of device would you like to see used, what peripherals/connectors?I actually thought hard about what kind of board would be interesting to design. I figured that my board covers the low end (if you delete the DDR2, you can do all the way down to the smallest S7-6) to low-ish middle, then there are Digilent's Arty-S7's, and finally SP701 which has pretty much everything you will ever need on a board. That's why I never actually went on to design anything with these devices. The only thing that I can think of as really missing is a board with SODIMM DDR3(L) slot so that you can load a crap ton of memory into it.

content: Well, the Arty S7 has relatively few IOs broken out. The Xilinx one is nice, but a bit expensive. But that's still very few boards compared to the tens of dev boards one can still find for the Spartan 6...As I see it, the Spartan 7 just seems not to be taking off like the 6 did when it got released. Maybe it will happen over time, but it's slow for some reason. Maybe it competes with the Artix-7 in a way that makes it look slightly unattractive. Dunno. I do have a couple Artix-7 boards.As for your own board, it should be fine for my needs. It's just that I haven't had time to build one as of yet. Otherwise, typically something with DDR3 and a comfortable number of IOs broken out would do.Also am in sort of a dilemma right now, as Vivado stopped working on Win 7 since last version. But I still don't really want to switch to Win 10, besides I have some peripherals that are not supported in 10 either and that I want to keep. Solution would be to use Vivado on Linux. Are you guys all on Win 10 now?

content: Quote from: SiliconWizard on March 19, 2021, 10:16:00 pmIf existing boards cover most needs, there is no need for that many. Like I said, when I investigated the market, the only two things I found missing were SODIMM DDR3(L) slot and SYZYGY-compliant connectors for cases when you need some amount of high-speed lines, but don't need so many as to use bulky and expensive FMC connector. And I didn't think that designing such a board would make a lot of sense.Quote from: SiliconWizard on March 19, 2021, 10:16:00 pmArtix-7 and Spartan-7 have the same fabric and all hard IP blocks (aside from MGTs and PCIE obviously), so Artix-7 can do everything Spartan-7 can, which is yet another reason there aren't that many S7 boards. S7 excels over A7 when you need a crap ton of IO, which is why SP701 has got so many stuff on it. For example, there are enough pins in 484 package of S7 to implement TWO 64bit SODIMM slots, and still have an almost IO bank for other stuff! 676 one would leave you too full IO banks (100 IO balls) after two SODIMM slots. That's a lot of IO pins!Quote from: SiliconWizard on March 19, 2021, 10:16:00 pmMy board as-is only has like 20 odd GPIOs, which of course it not very many. I would much rather prefer F256 package, but alas, S7 are not offered in that package.Quote from: SiliconWizard on March 19, 2021, 10:16:00 pmI use both Win10 and Ubuntu. Upgraded my Win7 installation shortly after Win10 came out, and never looked back since.

We've got quite a few products in the field, and ... we never bought a single development board.I don't understand the obsession with dev boards. You either design products or you're a hobbyist, and the hobby market is not interesting to Xilinx, certainly not to the point where they'll bother with an Ultrascale-based board to blink some LEDs.

content: You've got to stop hijacking this threadBack to topic - I've made it to the webcast, and here is what they said (aside from a ton of marketing mumbo-jumbo of course):- The motivation for Artix US+ is that while compute abilities are good, transceivers are out of date. Hence 12.5/16G transceivers.- The smallest A10 part is going to be roughly at the level of A75T in terms of amount of logic, a15 and 20 will fit between A100 and A200.- only smallest two parts will have PCIe 4.0 hardware support, top two members will only support PCIE 3.0x8 unless PCIE 4 is implemented via soft IP. The reason being that largest parts were designed before PCIE 4 requirement became a thing- All Artix US+ parts will be included in free WebPack license (yay!)- Largest two parts are going into production in Q3 2021, smaller devices - Q4 2021 or Q1 2022- They are working with third parties to design devboards- Tools support will came in 2021.1.1, because 2021.1 was already fully booked for other stuff. 2021.1 will come out in June, 2021.1.1 - July- Smallest Zynq US+ (ZU1) is in pre-prod right now, full production is late Q2/early Q3

content: Quote from: NorthGuy on April 08, 2021, 04:39:00 pmWell if you look at the Digikey, it seems that DDR4 is harder to source, while DDR3 is still plentiful. But I agree, DDR4 is a more future-proof solution, and they also can provide higher capacity (once chips larger than 4G will become widely available) at lower price, all while providing higher bandwidth as well. That said, technically nothing stops you from implementing a DIMM/SODIMM slot and buying a module at any computer store and use that instead of soldered-on chips, but that solution has it's own drawbacks (like higher power consumption, or larger physical board size).They also highlighted that HP pins natively support MIPI up to 2.5 Gpbs per pin pair, infact the case study they presented was a hi-res camera, which also uses their new chip-scale InFO package with 0.5 mm ball pitch. I wonder if these can be utilized as general-purpose differential signals, as latter would open up some interesting options like implementing some serial protocols which were only possible using MGTs - like PCIE 1.0, or DisplayPort RBR, HDMI 1440p, and 2.5G Ethernet.Also US+ DSPs with 27x18 multipliers running at up to 775 MHz is a serious compute power too, and even the smallest AUS+ will contain 400 of them.Quote from: NorthGuy on April 08, 2021, 04:39:00 pmThey said preliminary pricing as available under NDA if you talk to your sales rep, but since the parts we are most likely going to be interested in (smaller AUS+) are not even in pre-prod yet, it's too early to say anything for sure. Heck, they don't even have confirmed final pinouts, nor have they done any characterization to see what the real performance is going to be like exactly - hence the lack of official performance datasheets, only marketing mumbo-jumbo about what they are aiming for.

content: Quote from: SMB784 on August 05, 2021, 03:04:16 pmYea, that's the great news. I was kind of afraid that they price them way too high. My guess is they are going to be about US$100-120 for AU10P, about US$170 for AU15P, and somewhere around US$220 for AU20P, which is certainly not cheap, but I've built and hand-assembled a number of boards with Artix A75T and A100T for my clients and I'm quite comfortable working with US$150-200 chips, so I'm certainly looking forward getting my hands on these devices and making some cool projects.They've also announced an Opal Kelly's devboard with AU25P at US$1300 shipping in October. That's a bit overpriced in my book for a device with a price somewhere around US$300, but then it's just about 30% more than Genesys 2 board with Kintex-325T device with roughly the same resources as AU25P (aside from faster transceivers, IO and fabric). But I love that they've stuffed a whole bunch of SYZYGY connectors on this board, so maybe I will buy one - will see. One thing I don't like is that they've just placed a single DDR4 x16 memory device. I would really like to see at least x32 memory interface for the kind of IO that this board has.Finally, Xilinx typically makes a recording of a webinar available on-demand in a few days after it happened, so if I remember, I will post a link to it once it appears. Unfortunately they didn't answer my question regarding USB 3 5/10G physical signaling support in their transceivers (or I missed it - was in a virtual meeting at work at the same time), so I guess we will see about that too.

content: Quote from: SMB784 on August 05, 2021, 03:04:16 pmThanks for the news.For me it's clear now that Artix US is not the replacement for Artix, for some applications US suits much better, but for others Artix is fine.

content: Quote from: EEexpert on August 05, 2021, 03:39:37 pmWell it could be a good replacement for higher end Artix devices, as long as you don't require massive IO count some of those old Artix'es have.But what is interesting is that they effectively undercut their low-to-midrange Kintex-7 devices (again, provided that you won't require an extra IO of Kintex'es). If you look at AU25P vs K325T, in appears that the former is better in just about any metric, and, importantly, it's available with a free license (you have to buy a license to use K325T devices). Similarly, AU10P seems superior to K70T, as is AU20P to K160T - new devices are faster, cheaper, support modern and faster memory and IO standards, and more power-efficient.Also 16G transceivers allow connecting modern fast ADC/DACs via JESD204 interface, something that was simply not possible before, as these devices typically run interface at 12-16Gbps.

content: A bump to the topic:Last week I got an email from Xilinx telling these devices are now in production and instucting to contact sales. And so I did to see if I can acquire a few samples of AU10P or AU15P to build my own devboard (which is what I usually do for any new device I'm potentially interested in), we'll see what they say - that is if they get back to me at all

content: They need to focus on producing what they already have. FPGA companies do not need to be introducing new products when they can't build the ones people already rely on.

content: Quote from: SiliconWizard on April 29, 2022, 02:33:16 amAnother factor is that different product families use different fab processes, so bottleneck on one process doesn't stop proceeding with another one for a different product. And finally these orders are typically locked in a year or more in advance, so even if they were to decide to change their orders now, it will be well over a year until the actual effect of the change will be seen.

content: With the shortage, people tend to focus on the shortages as if no product were being shipped. The reality is there are literally tons of components being shipped. The demand is just outpacing supply.So, of course the semi companies are not going to sit around, without planning for the future. They have to keep ahead of the competition and keep up with the technology if they expect to find a rainbow at the end of the storm.
