The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

FPGA NTP Server
Interesting project, especially to gain insights into the FPGA programming part.
I think it is essentially a mixture of PTP and NTP now.
I guess this will work within the same local network, as the major inaccuracy of NTP comes from the asymmetric path delays at the network layer over the Internet.
PTP solves this by incorporating these hardware timestamps exactly. But this works only within the same LAN.
Here is an interesting PTP core:

Yes it is "old" but that is typically fine with HW projects.

You might find this repo interesting.
I have a 500 MHz oscilloscope on hand so I can decently measure the offset between the raspberry pi PPS and GPS PPS.
What are some alternatives?
