Verilator interactive example

The example under verilog/interactive showcases how to create a simple interactive visual Verilog example using Verilator and SDL.

You could e.g. expand such an example to create a simple (or complex) video game for example if you were insane enough. But please don't waste your time doing that, Ciro Santilli begs you.

The example is also described at: stackoverflow.com/questions/38108243/is-it-possible-to-do-interactive-user-input-and-output-simulation-in-vhdl-or-ver/38174654#38174654

Usage: install dependencies: then run as either: Tested on Verilator 4.038, Ubuntu 22.04.

In those examples, the more interesting application specific logic is delegated to Verilog (e.g.: move game character on map), while boring timing and display matters can be handled by SDL and C++.
