VHDL library for 108th and 109th ITC hardware.
Under src/, every hardware have its own .vhd file, consists of one package, which can have one or more constants and components.

There are no actual complete VHDL testbench, but there some .vhd files located under tests/ you can Set as top level entity in Quartus to test some of the packages.
Under tools/ there are scripts that help with the writing of the code.
