本书的主要的服务对象是熟悉硬件系统，而对软件的设计经验缺乏的工程师；叙述了VHDL的用法-This guide is intended for the engineer who is familiar with the principles of

hardware design, but has little experience in designing with a language-based

synthesis system. It describes the general concepts of synthesis, the general

organization and usage of VHDL, and provides specific information on how the

Metamor tool is used in this environment. It does not attempt to present the VHDL

language in depth, but does provide an example-based summary of VHDL syntax

that serves as a helpful reference for any user.
