I got springs, intended to use those under the screws but didn't have any long enough. They are barely tight for now until I get longer screws.
Where's that 100 A FPGA meme?
I've not really pushed the buffer board at all, have not had a heatsink on it until today. Xilinx XCKU5P docs specify a 52 amp maximum for VCCINT with the FFVB676 package. I'm taking that as a challenge, this board is capable of 80 A.
A bunch of my AES cores to use up the LUTs and FFs, my cosine cores to use the DSPs and BRAMs will do a good job of loading all of the resources for power testing. I'll be doing load step in addition to maximum power testing.
@aleksorsist It's an EMI absorber like this: https://www.kgs-ind.com/products/emc/ferrite-core/sheets-tiles/sd/
Those big QFPs are awful for EMI with the long bond wires.
@azonenberg Some day, we will be back to making a phone call and reading part numbers to an operator like I did for my first ever distributor order back in the late 90's.
I've actually been tempted to try it for a small order when the website was blocking me.
@azonenberg I've not ordered from Mouser in a long time. They used to at least be cheaper than Digikey. Not any more. They also charge the tariff on their whole inflated price so are profiting from it. Digikey is less bad there.
Digikey dumped my whole cart last week after going down, I couldn't find any way to recover wasting a bunch of my time. There's also the "ATTENTION: Due to high order volume, orders may require up to 4 additional business days to process."
Can we have 2019 back?
