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.

1800-2023 – IEEE Standard for SystemVerilog
I'd love to see textual preprocessors kinda banned. Or at least done upstream and outside of the language. You can't both be and also have a textual preprocessor defined internally. It doesn't work.
I really like what Zig and C++ are doing with `const`.

Ao486_MiSTer: i486 core for the MiSTer FPGA gaming system
Many companies do just write entire modern SoCs in straight Verilog (maybe with some autogenerated Verilog hacked in there) with no other major organization tools aside from the typical project management stuff. The load-store unit of a modern CPU alone easily exceeds 10k lines of Verilog. It's a similar thing as people who work with kernels—after all, the page table management code in a modern operating system like Linux is absolutely monstrous but still people are able to understand it well enough to be able to make the changes they need and get out.
If you are interested in other languages which hope to make this sort of stuff easier, I'd recommend taking a look at design productivity languages like Chisel and it's associated Chipyard [1], SpinalHDL [2], and Bluespec [3]. Each of these are meant to make defining extremely complex hardware more manageable for humans and there's a lot of interesting work going on right now with each of them.

Simple skid buffer implementation
I have just found that SpinalHDL also implemented two halves of the fully registered buffer in Stream.scala.

Why are there only 3 languages for FPGA development?
Don’t forget SpinalHDL that was forked off of Chisel 2 I believe. These DSLs really leveraged the software features of Scala to help build generalised/modular systems. And are generally a quality of life improvement in the language features available.

Share some github FPGA projects (bonus if they include C++, Python, or other files)
A lot of reuse from other FOSH projects, including Litex, SpinalHDL, betrusted & u/alexforencich verilog-wishbone. Thanks to all of them :-)

Suggest advance project ideas
You could try to implement a PCIe root complex for FOSS SoCs, connecting to e.g. Wishbone as the main bus. There's already some DDR3 controller (or this one) and USB Host controller out there, and even device-side PCIe, but no FOSS host-side PCIe that I know of. Probably quite a difficult job though, even sticking to the lower-speed PCIe 1.

Quartus Tcl Build Script
Tcl, not sure, but I have done it with makefiles. See https://github.com/alexforencich/verilog-ethernet/tree/master/example/C10LP/fpga.

Using Si5324 as a clock generator on virtex-7 board
For that part I think you need to use the software from silicon labs (might be skyworks now) to generate the stuff you need to write to the registers. Then, you can use something like https://github.com/alexforencich/verilog-i2c/blob/master/rtl/i2c_init.v. See https://github.com/alexforencich/verilog-ethernet/tree/master/example/HTG9200/fpga_10g for an example that targets the Si5341 specifically.

DE2-115 Ethernet Network Setup
For a personal project I'm trying to send data via Ethernet from my laptop into the FPGA, where it has some filtering and other processing done to it, then back into my laptop. I've been trying to get this repo to work, but there's a problem: my ancient macbook can't run Quartus, so I need to use campus PCs to build the project and program the board, but I don't have permissions to successfully run the makefiles that build the project.

ROS 2 Humble in AMD KR260 with Yocto
No there's none. Not in this post at least, but it certain is being used. If you're interested in that, follow my progress at https://github.com/alexforencich/verilog-ethernet/issues/146 (or stay tuned/reach out to Acceleration Robotics for early previews and support) for a 10G NIC on the KR260.

Choice of LFSR When implementing the ARP Cache in a UDP Stack
So, im trying to understand the UDP implementation in verilog-ethernet. In particular I am looking into the ARP Cache and have a query.

Preference for Combinational or Sequential design?
I've been studying u/alexforencich's ethernet library since I'm working on a similar project. I've been noting his interesting design style. When I think about a solution for a problem, I immediately naturally thing about a sequential design whereas he has tons of combination logic in his designs.
