Specification of Digital System

Specification of a system is the description of its function and other characteristics required for it, for example speed, cost and power.

Design can be improved at the expense of worsening on both of the others. These tradeoffs exit at every level in the system design, every sub-piece and components. A designer must make the tradeoffs necessary to achieve the function within the components.

A specification should have following properties:

• Simple but complete.
• Interpretation is unambiguous.
