To get started with learning FPGA easily, it’s best to begin with Free and Open Source Software (FOSS). The first tool you’ll need is a Synthesizer.

I. What is Docker? What are the benefits?

Docker is an open-source platform for automating deployment, scaling, and management of applications as containers.

II. Installing Yosys in Docker

Follow the instructions here to install Docker first.

a. The Dockerfile

FROM ubuntu:20.04
ARG DEBIAN_FRONTEND=noninteractive
ENV TZ=Europe/Paris
RUN apt-get update; apt-get -y install curl
RUN apt-get install -y build-essential git clang bison flex     libreadline-dev gawk tcl-dev libffi-dev git     graphviz xdot pkg-config python3 libboost-system-dev     libboost-python-dev libboost-filesystem-dev zlib1g-dev
RUN git clone https://github.com/YosysHQ/yosys.git yosys
RUN cd yosys; make -j$(nproc); make install
WORKDIR "/project/"
ENTRYPOINT [ "/bin/bash", "-c", "yosys src/synth/synth.ys > build/logs/syn_log.txt" ]

b. Building the image

docker build -t yosys .

III. Project Workspace

Makefile
src:
  synth:
    - synth.ys
  hdl:
    - top.v
build:
  logs:
  artifacts:
    syn:
    pnr:
    bitstream:

// top.v
module top( input clock, input resetn, output reg LED );
  reg tmp = 1'b0;
  always @(posedge clock) begin
    if(!resetn) tmp <= 1'b0;
    else tmp <= ~tmp;
    LED <= tmp;
  end
endmodule

Use the Makefile or Docker run commands as described...

I really want a picture here!!
