面向对象的VHDL模拟器

Object-Oriented VHDL Simulator

从面向对象技术角度出发 ,论述了 VHDL 编译型模拟器的构造方法 ,以及面向对象的封装、继承、多态技术在 VHDL模拟系统构造中的应用方法 .提出了由三部分组成的编译型模拟器总体结构 :模拟核心、调试核心和用户 VHDL 源描述所转换而来的 C++代码部分 .此种结构的面向对象编译型模拟器具有速度快、结构清晰、可扩充性强等优点 .最后用实例验证了该结构的效率与性能 .

The general structure of VHDL compiled-simulator is presented. It contains three parts, that is, simulation kernel, debug kernel and C++ source code, which is translated from the user VHDL source. It is proven that this kind of simulator has the advantages of high speed, being well structured and easily extendible. Tests verified the performance and efficiency of the structure.
