Before (at 1.024 Gbps) it had slipped in one direction at 210 MHz and the other direction at 290 MHz. This indicated that there was a clock rate problem.

Once it was running at 200MHz the slipping was random. Random slipping indicated to me there was also a signal integrity problem and the clock rate problem was fixed.

I had soldered a termination resistor on that proto-board (0201... yikes!) because #Xilinx doesn't allow internal resistors on this bank.

On a hunch I added attenuators...

There are #Framework13 models now with #AMD CPUs! This is getting interesting for many reasons! 👀

1. The AMD Ryzen AI CPUs come with a #NPU based on #XDNA from the #Xilinx acquisition. In practice #AMDXDNA only made it into Linux 6.14 (e.g. in the very recent Fedora 42) and there is no end user support as of today making the NPU dead hardware as of today and probably most of 2025.

2. The AMD Ryzen CPUs come with AVX512 and that's working end to end unlike whatever the f #Intel is doing there.

#FPGA dorks. I'm running into an issue where #vivado says: multiple drivers on MMCM pins when I use a known good block (LVDS deserializer from appnote xapp523) in the vivado block diagram for a 7 series #xilinx #zynq part (snickerdoodle black). I get the error even if I pin out directly to top level pins. I hate using the gui because it hides too much magic. Has anyone hit this madness before?

I'm trying to deserialize a 1.024 Mbps 8b10b lvds to get it on the linux side for storage on disk.

Neue Hauptplatine für das Commodore 1541-Diskettenlaufwerk, Teil II

#AMD Moves Up Instinct #MI350/#MI355X To Now Release By Mid-2025, #MI400 Lineup Slated For 2026 As #Datacenter Biz Hits Records
Last year the datacenter business at AMD, which includes #EPYC #CPU, Instinct #GPU, #Pensando #DPU, and #Xilinx #FPGA accelerators, accounted for $12.58 billion in sales, or 48.8% of revenues. In both Q3 and Q4 of 2024, datacenter drove in excess of half of AMD’s revenues and nearly 60% of its operating income.

The Next Platform · AMD Moves Up Instinct MI355X Launch As Datacenter Biz Hits RecordsWhen we first started The Next Platform a decade ago, there was not really much of a reason to cover the company’s datacenter efforts. But, we are a

Et voici un #AtariST un peu étrange ! C'est une carte MicroPhase Z7-Lite avec un SoC #Xilinx Zynq (un processeur #ARM + un #FPGA), avec le logiciel ZeST de @zerkman à l'intérieur !
La partie matérielle d'un #Atari STF y est décrite en VHDL et tourne dans le FPGA (y compris le processeur 68000). Clavier/souris sont en USB et la vidéo en HDMI.
On peut mettre des images de disquettes et de disques dur sur la carte SD, il y a un petit Linux dans l'ARM qui permet de rendre visible le contenu des fichiers à la partie "silicium" contenue dans le FPGA (si j'ai bien compris le principe).
C'est très chouette tout ça :-)

#AMD Publishes #XDNA #Linux Driver: Support For #Ryzen #AI On Linux
The XDNA driver will work with AMD Phoenix/#Strix SoCs so far having #RyzenAI onboard. AMD has tested the driver to work on Ubuntu 22.04 LTS but you will need to be running the Linux 6.7 kernel or newer with IOMMU SVA support enabled. The #Xilinx XRT software also needs to be built to work with this kernel driver. So far is a simple test script for verifying that your driver stack is currently setup.

@WillFlux This is sometimes helpful. In the #Xilinx tools I tend to bump the version number and rebuild if it misses timing by a small amount. Promising #reproducibility in these tools is hard. In #Vivado it's only "guaranteed" if you turn off all of the parallel processing. And even then I think you really need to run it on the same hardware. And even then I wouldn't be confident, because I don't think anyone at Xilinx tests for reproducibility. A 'fix' might pre-process to remove all comments.
