Behavioral Modeling in using HDLs

Abstract

This chapter introduces the concept of behavioral modeling. There is a real need to abstract to a higher level in many designs to make the overall system level design easier. There is less need to worry about details of implementation at the system level if the design can be expressed behaviorally, especially if the synthesis method can handle any clock, partitioning or implementation issues automatically. Using system level, or behavioral, analysis, decisions can be made early in the design process so that potentially costly mistakes can be avoided. Preliminary area and power estimates can be made and key performance specifications and architectural decisions can be made using this approach, ...
