Verilog® HDL: A Guide to Digital Design and Synthesis, Second Edition

Chapter 7. Behavioral Modeling

With the increasing complexity of digital design, it has become vitally important to make wise design decisions early in a project. Designers need to be able to evaluate the trade-offs of various architectures and algorithms before they decide on the optimum architecture and algorithm to implement in hardware. Thus, architectural evaluation takes place at an algorithmic level where the designers do not necessarily think in terms of logic gates or data flow but in terms of the algorithm they wish to implement in hardware. They are more concerned about the behavior of the algorithm and its performance. Only after the high-level architecture and algorithm are finalized, do designers start focusing on building the digital ...
