#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.

maybe someone with #fpga know-how here can help me out:

I have a couple of iCE40UP5K boards lying around. Any chance I can put them to use as a composite video digitizer (ideally USB video class)? It only has 1024Kb of SRAM, which is not enough for a full PAL or NTSC frame, but maybe MJPEG can compress it enough on the fly? Or can I send partial frames by UVC?

(where) can I find verilog/vhdl sources for the composite video decoding part?

I've got myself a new toy 🙌

This is the GateMateA1-EVB from Olimex, an FPGA dev board containing the GateMate CCGM1A1 with 20480 CPEs.

Now that initial nextpnr support for the chip has been merged, it is possible to program it with a fully open source toolchain 🎉
Synthesis with Yosys, place and route with nextpnr, bitstream packing with gmpack and finally upload to the board with openFPGALoader!

That meant I just had to get one, and two days later it arrived!

Eigentlich wollte ich von Dir wissen auf welchem OS das bei Dir läuft.

Es ist ein Unterschied ob Du Knoppix, ein Deb mit angepasstem Kernel oder Windows nimmst. 😁

Bevor ich mir eine teure GPU kaufe, würde ich eher zu einer Ki taugliche #FPGA GPU "Hardware" kaufen.

Z.B. einen Nvidia jetson

Et voici quelques nouveaux jouets qui viennent de chez @olimex : une carte #FPGA ice40 , une carte avec des connecteurs VGA et PS/2, et un clone d'Arduino (qui va servir pour programmer le FPGA).
Et le plus beau c'est que la suite de développement est 100% open source !

💸 Intel Sells Altera Business | Phoronix

「 A decade after Intel acquired FPGA maker Altera for $16.7 billion and recently working to make Altera an independent company, Intel announced today it has sold 51% of its Altera business in a deal that values that business at $8.75 billion.

Intel announced today that Silver Lake will acquire 51% of the Altera business 」
