   // ==========================================
   // For use in Makerchip for the MYTH Workshop
   // Provides reference solutions
   // without visibility to source code.
   // ==========================================
   
   // ----------------------------------
   // Instructions:
   //    - When stuck on a particular lab, configure code below,
   //      and compile/simulate.
   //    - A reference solution will build, but the source code will not be visible.
   //    - You may use waveforms, diagrams, and visualization to understand the proper circuit, but you
   //      will have to come up with the code. Logic expression syntax can be found by hovering over the
   //      signal assignment in the diagram.
   //    - Also reference https://github.com/stevehoover/RISC-V_MYTH_Workshop/blob/master/README.md
   //      for updated information during the workshop as well as live support links.
   // ----------------------------------
