SDL在数字系统设计中的应用

Application of SDL in the Digital System Design

作为一种标准的形式语言 ,SDL已经被广泛地应用在软件设计中。为了进一步扩大其应用领域 ,进行了在硬件方面的应用探索。以逻辑门电路—与门为例 ,以SDT为工具 ,说明了应用SDL进行特性描述和仿真 验证的方法。由于SDL支持面向对象技术 ,所以可以把各种常用逻辑电路或数字电路设计为SDL包。通过引用这些包 ,就能够描述和仿真 验证复杂的数字系统了。实践证明 ,SDL在硬件方面的应用是可行的 。

As a standardized formal language, the SDL has widely been used in the software development. In order to extend its application field, it has been explored to use in hardware design.This paper gives a logical gate circuit-and gate as an example to explain the method of applying SDL to describe and simulate/validate the hardware characters by the SDT tool. The various logic circuits or digital circuits may be made to the SDL packages because the SDL supports the object oriented technology. These packages can be directly invoked in the design of the complex digital system, so it is possible to describe and simulate/validate the complex digital system.The experiment has proved that the application of SDL for hardware design is feasible and rather convenient.
