In Pure Silicon Demo Coding: No CPU, No Memory, Just 4k GatesThe 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.)

In Programming on Parallel Machines; GPU, Multicore, Clusters and MoreI'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.
In FPGA Dev Boards for $150 or LessI get paid to do this professionally so I don't follow the hobbyist side but I've heard of people using this for FPGAs. I have no idea how it compares to commercial tools.

OSS CAD Suite is a binary software distribution for a number of open source software used in digital logic design. You will find tools for RTL synthesis, formal hardware verification, place & route, FPGA programming, and testing with support for HDLs like Verilog, Migen and Amaranth.
In U.S. universities are building a new semiconductor workforceThere'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.
