There are useful tools able to use for simulating verilog codes in macOS. Here I use iverilog as a verilog compiler, vvp as a wave-file generator and gtkwave as a wave displayer. All of three can be downloaded through the package manager Homebrew:

brew install icarus-verilog
brew install verilator
brew install --HEAD randomplum/gtkwave/gtkwave
brew install graphviz

Notice that the name is not different...

There are various instructions for these on Internet...

However, I still can't figure these three kinds of tools out very clearly, just know how to use them in a simple way: scripts named create_wave.sh, wave_sim.sh and display_wave.sh in Simulate/.

Basically:

iverilog -o [wave_file] [.v_srcs]
vvp [wave_file] > results/result_*
gtkwave [.vcd_file]

.vcd_file means the file dumped by testbench file.

On Windows, we are required to use ModelSim for simulating and Vivado for loading the codes to FPGA(Nexys 4 DDR2). I don't find any substutional software in macOS for the latter. Welcome to inform in the issue...

ps: Both of two are for developing using MIPS Assembly Language.

Great thanks to the repository of scarletborder. 🙏 It was of great help after my own design failed... 🥺

The report...etc.
