Introduction to
VHDL
The VHSIC Hardware Description Language is an industry
standard language used to describe hardware from the
abstract to the concrete level. VHDL resulted from work
done in the ’70s and early ’80s by the U.S. Department
of Defense. Its roots are in the ADA language, as will be
seen by the overall structure of VHDL as well as other
VHDL statements.
VHDL usage has risen rapidly since its inception and
is used by literally tens of thousands of engineers around
the globe to create sophisticated electronic products. This
chapter will start the process of easing the reader into
the complexities of VHDL. VHDL is a powerful language
with numerous language constructs that are capable of
describing very complex behavior. Learning all the features
of VHDL is not a simple task. Complex features will be
introduced in a simple form and then more complex usage
will be described.

2 Chapter One
In 1986, VHDL was proposed as an IEEE standard. It went through a
number of revisions and changes until it was adopted as the IEEE 1076
standard in December 1987. The IEEE 1076-1987 standard VHDL is the
VHDL used in this book. (Appendix D contains a brief description of VHDL
1076-1993.) All the examples have been described in IEEE 1076 VHDL, and
compiled and simulated with the VHDL simulation environment from

1引言vhdl的VHSIC硬件描述语言是一种行业标准语言来形容,从硬件 抽象到具体的层面. vhdl因工作,在七十年代和八十年代初,由美国国防部. 其根在Ada语言, 我们将看到的整体结构的VHDL以及其他vhdl报表. VHDL的应用已迅速上升,自成立以来,目前正被字面上数以万计的工程师前后 全球制造精密的电子产品. 这一章将开始着手缓和读者进入复杂的VHDL . vhdl是一个强大的语言与各种语言结构,可以描述非常复杂的行为. 学习的所有特征vhdl并不是一个简单的任务. 复杂的特点,将推出一种简单的形式,然后在更复杂的使用将会有叙述. 2月1日第一章1986年vhdl建议作为IEEE标准. 它经历了若干修改和变化,直至获得通过,成为IEEE的标准, 1076年12月 1987 . 在IEEE 1076-1987标准vhdl是vhdl用这本书. (附录D包含简述vhdl 1076-1993 ) . 所有例子被描述在IEEE 1076 vhdl , 编制和模拟的VHDL仿真环境
