learn-fpga VS litex

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.

Lattice Icestick is pretty cheap and has just enough LUTs to run a small riscv. Also check out https://github.com/BrunoLevy/learn-fpga

Thanks Bruno Levy

These are good starting points: https://github.com/BrunoLevy/learn-fpga/ and, from there, https://github.com/BrunoLevy/learn-fpga/blob/master/FemtoRV/README.md.

The best point-of-entry for "tiny" MCUs these days is FemtoRV32-Quark or SERV. I also maintain my own small RISC-V core (Minimax), though it's early on in graduating from "experiment" to "real design".

Rust blinky on RISC-V soft core If you were looking for, an introduction example of an embedded Rust program, running on a RISC-V soft core, check out this blinky that is using the FemtoRV .

Nope - that's all there is.

It's possible to be incredibly expressive in Verilog and VHDL. This implementation is written in VHDL, which has an outdated reputation for being long-winded.

Also worth a look: FemtoRV32 Quark [0], which is written in Verilog.

they have tutorials, you can get compatible boards for around $20

With LiteX you can synthesize a VexRiscV processor. You can run Linux on it. The toolchain is pretty easy to use, as long as you use Xilinx Vivado to compile to gateware.

LiteX is a great example of a Python-first flow. However, they have chosen not to subordinate the scripting environment to a GUI toolchain - EDA vendors are unlikely to choose the same trade.

To lean these: https://github.com/enjoy-digital/litex, https://github.com/m-labs/migen

If you use LiteX to generate a VexRiscV system-on-a-chip, you can include an open source DDR DRAM PHY. This works on Xilinx Spartan-6, Spartan7Artix7/Kintex7/Virtex7 FPGAs, and Lattice ECP5 FPGAs. DDR/LPDDR/DDR2/DDR3 depending on the FPGA.

I am interested in trying out FPGAs for the purpose of running specific calculations more efficiently. Since the calculations themselves are quite complex, I would need to be able to program in a relatively high-level language. I've seen that designing SoC in Python is possible, for example with Litex (https://github.com/enjoy-digital/litex) or Amaranth (https://github.com/amaranth-lang/). I don't want to spend hundreds of hours learning about FPGAs, but I'm prepared to take on a challenge.
