As a long time Altera user, one of the biggest things that made me want to jump the fence to Xilinx was the MUCH stronger community and hobbyist uptake. Xilinx benefitted from a ton of people out there educating others on their behalf.
Trying to shrink that community seems like a pretty obvious error. The closest thing the Altera world ever had were the old Altera user forums, which were a gold-mine. Intel shut them down immediately on acquisition. I guess it's AMD's turn.
The HBM stacks are on-package for these parts, so you don't have to use any external I/O to interface with them.
You end up with a similar challenge accessing that much bandwidth internally from your FPGA logic though, it looks like the Xilinx HBM IP presents a set of 16 or 32 separate AXI interfaces, each of which gives you about 14.4GB/s of bandwidth (https://docs.amd.com/r/en-US/pg276-axi-hbm/Introduction).
PTP is a great choice when you need your time-sync to leave the software domain, for instance, locking an external PLL for frequency and phase aligned clocks.
PTP enabled MAC's and PHY's usually have a dedicated hardware output for a PPS (pulse-per-second) or faster clock, generated directly from the hardware PTP counters.
In the video world, we get great results synchronizing software events with NTP, but whenever you jump to a physical interface (DisplayPort, HDMI, SDI, etc.), NTP-based clocks are far too jittery.
I've seen some work using the PTP hardware in the MAC with the NTP protocol, a sort of hybrid approach, but don't have any first hand experience.
We develop audio, video, and show control systems for themed entertainment. You'll find our equipment in the world's biggest theme parks, museums, and attractions.
The hardware (down to the PCB), firmware (from FPGA's to RTOS's), and software (C++/Qt) are all engineered in house. We're looking to hire great engineers with any mix of experience in FPGA's, embedded systems, and desktop application development.
It's amazing to see the things our creative customers do with our products, and it's exciting to work on next-generation tools and hardware to enable our customers to create the "next-big-thing".
If you'd like to chat about it, my contact info is in my profile. For more details and to apply, you can check out the job listings on our website: https://alcorn.com/about/careers/
