The trend of Very Large Scale Integration (VLSI) circuit designs is towards greater density and complexity. A decade ago, the size of chip designs ranged from tens of thousands to hundreds of thousands of components. Today, they consist of millions of components. This increase in chip density means that complex designs with more functionality can now be implemented as a single chip. An effective way to deal with the increasing complexity of designs is to raise the level of abstraction at which circuits are designed. High-level synthesis refers to computer-aided design approaches starting from the algorithmic description level. The benefits of such a methodology include shortened design time to reduce design cost, ease of modification of the hardware specifications to enhance design reusability, and the ability to more effectively explore the different design tradeoffs between the area and performance of the resulting hardware.
