Any Digital Logic Design ideally starts from the specification. Specification is about listing the probable features and input output selection.

These I/O relations — creations, and the processing can be handled by digital circuit. These circuit may include some processing unit like processor, or ASIC, or IC or discrete components.

Selection and Gathering this components will be the good and sufficient process initiation for any Digital Logic Design Project.
