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.

Programming on Parallel Machines; GPU, Multicore, Clusters and More
The OSS CAD Suite [0] is a good open-source toolchain for this stuff. You can then write hardware designs in the SytemVerilog language (VSCode has some plugins, I believe, but I've just been using a basic text editor) and use the build toolchain to compile ("synthesize") and program e.g. an FPGA with your designs.
(FWIW, I've only just taken a class on Verilog this past Spring, but we used oss-cad-suite and I found it pretty straightforward to use. The bundled version of Verilator had some issues on my Mac though, so I had to compile my own copy of Verilator.)

FPGA Dev Boards for $150 or Less
I've followed this tutorial recently, and it's amazing:
https://github.com/BrunoLevy/learn-fpga/blob/master/FemtoRV/...
The author includes detailed instruction for how to build a micro-controller in Verilog on an icestick, starting from a very simple blinker all the way to a functional RISC-V core.
My other suggestion would be: for most of the toolchain, skip your package manager and directly install the binary artifacts published on this Github repo:
https://github.com/YosysHQ/oss-cad-suite-build
You'll spare yourself a world of pain.

Development board for beginner: where to buy
You can compile and install from source or you can install the TabbyCAD software suite. It can be freely downloaded here: https://github.com/YosysHQ/oss-cad-suite-build.

help with open source VHDL synthesis
I use a pre-built suite of tools from Yosys called the OSS CAD Suite, you can find binary builds at https://github.com/YosysHQ/oss-cad-suite-build

How to update GTKwave?
OSS CAD Suite gives you the absolute latest version of GTKWave (3.4.0), plus Icarus Verilog and a bunch of other stuff. On Windows though you need to use the start.bat or environment.bat scripts though to make the tools available in a command prompt.

Introduction to FPGAs
There's a darwin-arm64 asset for https://github.com/YosysHQ/oss-cad-suite-build/releases at least. Installation is just 4 steps (see the readme). It just worked for me on Windows and Linux at least.

(System)Verilog Linting in VSCode?
You’ll need to install the latest iverilog version. The easiest way to do that is to install https://github.com/YosysHQ/oss-cad-suite-build

I really liked the OSS CAD Suite collection put together by YoSYS so I made a version manager for it
I'm a macOS user that's recently been looking for a great FPGA development workflow for macOS. I recently discovered this collection. I liked that this was a nightly build but wanted a way to maintain the version of the tool suite used with my sources so I built a version manager for it here https://github.com/nishtahir/icicle. I'm still testing it and ironing out the kinks but would appreciate any feedback.

Do you work in a mixed HDL shop?
It also seems like YosysHQ's prepackaged OSS CAD Suite ships with the GHDL plugin, making installation a breeze compared to building from source (just extract the suite and add to PATH).
-
Is there a Free, open source FPGA programming software?
The other is oss-cad-suite which is a more traditional binary distribution in the form of a tar ball that you download, extract and add to your path.

YoWASP aims to distribute up-to-date FOSS FPGA tools compiled to WebAssembly
If the name were an arbitrary word which didn't attempt to define itself, would that be any better? I don't see why the name must mean anything specific, nor why you should expect the name to explain what the project is. That's what the documentation or other descriptive text is for. That the name gives some understanding at first glance is a bonus.
PnR is "place and route", and is a very common acronym in the ASIC/FPGA/VLSI space. It seems fair to expect those who'd use this specialized variant of Yosys to also be familiar with PnR. For reference, here's [1] Yosys's PnR tool, which expands the acronym in its README title.
Realistically, if you're using Yosys tools, you're going to need to have some familiarity with the underlying flows anyway; in my experience they're very powerful but also pretty DIY. That's not great, but it's the reality. That's just the nature of the space right now, given the alternative is a ~$1M single user license.

Is there a Free, open source FPGA programming software?
Check out Nextpnr. There's only a few lines it supports, but it is expanding. Smaller devices are especially well supported.

Sobel Edge Detection with Icestudio and ULX3S FPGA board
I'm not much aware if it's already considered fully supported but as answered on this issue, ECP5 is the best supported FPGA for the toolchain(but its talking about nextpnr specifically tho). But personally, I found no problem with it.
