Introduction
Hardware design in electronic system level (ESL) is becoming mainstream, but there are still a lot of questions about its generality. Many engineers believe that the abstractions that are at the heart of the ESL design process are not applicable to a large subset of designs, particularly control-dominated designs. The purpose of this article is to show the value that design abstraction offers for control-dominated designs.

Abstraction
Abstraction is a concept that everyone has an intuitive understanding of, but few can cite a formal definition. We can define abstraction in a number of different ways. We can look at abstraction analytically, or we can look at the mechanisms used to implement design abstractions.
