摘要： 本文介绍了使用Ada作为硬件描述语言的初步结果。硬件系统可描述为一系列分类的对象,每个对象是一抽象数据类型的体现。类型的定义及其操作都包含在一程序包内。形成分层部件描述系统。时间和物理因素亦可在定义中描述。硬件设计者可对该系统进行模拟、组建和合成。

Abstract: This paper surveys the recent development in using Ada as a hardware description language for integrated circuits. Hardware system is described as an ensemble of typed objects, where each object is an rinstanee of an abstract data type. The type definition and the associated operations are encapsulated by a corresponding package, thus forming a hierarchical component description system.Timing and physical considerations can also be represented in the specifications. Hardware designers can perform simulation, construction and synthesis on the system.
