unsigned counter with guardian bits

Counter with two guardians who count either even or odd position bit.

This repository is summarizing on my verilog review.

Tested on Ubuntu 20.04 WSL2.

I'm using iverilog and netlistsvg.

You can install from setup.sh.

 $ bash setup.sh

Build from iverilog.

We can check .vcd file waveform on GTK Wave.

 $ bash build.sh guarded_unsigned_counter

We can make nice RTL Diagram by using netlistsvg.

 $ bash netlist.sh guarded_unsigned_counter
