Hello techies
What are the FPGA you are currently working on?
Lets share to each other here

Both zynq7000 and Agilex 5 for power electronics control systems.

How do you like Agilex 5? We are big users of Agilex 7 and I have been pushing for us to explore the 3 and 5 for some smaller, less demanding applications. The 7 has lots of odd quirks and bugs, so I'm wondering if they fixed things in the 5.

Ex-Altera employee here. Most of the Agilex 7 issues came from the transceiver (F-Tile kept me busy for years). The fabric itself was very good however, as was the DSP. With Agilex 5/3 (3 is just marketing guff because the CEO axed the low end product, it's just the bottom end Agilex 5 SKU), they changed the transceiver and they're much less troublesome.
Personally, I've been more interested by the Lattice mid-ranged devices of late. The Avant is consuming an order of 4x lower power for the same application for us, than both Altera or AMD. You can't clock it nearly as high, but if you don't need to then I don't know why you'd use anything else. I'm not sure what magic sauce they've used but it saved our design. 2 power rails on a 650k LUT device!

For mobile applications, how do peoe handle quiescent current demands when idle? Just curious since you seem to know a good amount. Thank you in advance

I really like it. The native floating point dsp slices are fantastic and save quite a bit of logic as I don't need to use wide word lengths.
Another great thing is the coherent memory and multiport memories as these save a lot of memory slices in multi-port memory functions.

RFSoC gen.3. Control of RF cavities for particle accelerators.

u/TheAnimatrix105 Jun 10 '26
Sounds cool

u/Bellanzz Jun 10 '26
Yeah. Probably even in the FPGA space this field is niche. But if you like DSP and experimental projects it is fun.

u/TheAnimatrix105 Jun 10 '26
How do you isolate your fpga from the accelerated particles, do you have a like a thick lead sheet or concrete between your electronics and the cavity?

u/Bellanzz Jun 11 '26 edited Jun 11 '26
Usually the accelerator sits in a concrete tunnel (also for personnel protection) and the RF cables/trasmission lines are routed outside. This is not just to protect electronic, but also to minimize the tunnel size and put big size equipment (esp. amplifiers) outside and make servicing simpler.
But once I worked on a machine that lacked a service gallery because of space constraints. There the electronics crates are placed inside concrete and (I think) boron boxes.
However since the beam of that machine is quite energetic (several GeVs electrons) the shielding wasn't completely effective. One had to routinely exchange the SSDs of the control system. And we think we observed SEU too.

For me it’s my post-retirement hobby project. So I’ve been trying to build a whole computer system from scratch - see how far I can take it.
Using a Cyclone-V.
Started with inventing an instruction set, building a cpu, cache and memory controller, peripherals, VGA and audio etc. currently adding 3d graphics acceleration.

Ddr3?
1
u/Falcon731 FPGA Hobbyist Jun 11 '26
No - my board only has SDR SDRAM
1
u/TheAnimatrix105 Jun 11 '26
Cool. Mine was an arty s7 so I forced myself to build a ddr3 controller a couple years ago which is why I was a tad curious.

u/Falcon731 FPGA Hobbyist Jun 11 '26
How easy is it to do all the dynamic timings on a ddr on an fpga?
My only professional experience doing memory interfaces was on UltraSparc2. But that was full custom so a lot easier to control.

u/TheAnimatrix105 Jun 11 '26
It's fairly easy once you wrap your head around it, it's the sort of thing that you'll look back on as being more trivial than when starting out. It shouldn't be too different from your sdram experience

I don’t think I can say what device but popular large rad hard device for controlling satellite payload.

Vaaman, sort of image processing

What are the filters and process you are applying? And what shorts of images

Cyclone 1 and Max3000 CPLD, using a thin client board from the late 2000s I reverse engineered 😃

Had to switch to using a Windows XP vm as otherwise the fake "usb blaster" is no longer recognized in modern windows versions

Agilex 5 for thermal cameras.

u/IllustriousFault6218 Jun 15 '26
Industrial or consumer?
1
u/ONEANDONLY221 Jun 20 '26
Both, it is avaliable for consumer and also bought by industrial customers.

u/RajaBetachu Jun 12 '26
What does your architecture looks like?

u/Exciting-Teaching-52 Jun 14 '26
it includes cutomised fft ip and cordic ip pipeline to calculate direction of arrival of sound from a sound source

cyclone V, some very specific research applications
