The Decode Window is a special feature that essentially allows the user to operate the PLA Tool in reverse.
Imagine the user has a pla code file as part of a project but can't recall exactly which circuit it is supposed to implement, by clicking
on "decode" he can quickly decipher the code. By entering the hexidecimal values present in the code into the corresponding elements on the decode window, the tool
takes the values and uses them to reconstruct the circuit. This feature can also be used if the user loses the circuit's ".pla" file or if they simply want experiment
with the hex value.
The final section presents an example circuit and shows how it is implement with the PLA Tool.
