VHDL 模拟器波形显示器的研制

Design and Implementation of a Wave Viewer for the VHDL Simulator

目的研究图形、图像的快速显示算法，研制工作站环境下基于Ｍｏｔｉｆ的面向对象类库．方法在工作站平台上使用Ｃ＋＋和Ｍｏｔｉｆ研制了ＶＨＤＬ模拟器波形显示器．波形显示器中使用了波形图三级映射算法．构造并使用了Ｍｏｔｉｆ的面向对象类库．结果该波形显示器具有显示速度快、程序可移植性强等特点．结论充分体现了算法的优越性和基于Ｍｏｔｉｆ面向对象类库设计的合理性．

Aim To study the fast display algorithm for graphics and image,and to develop an object oriented class library used for Motif under aworkstation environment Methods A high performance VHDL wave viewer is developed on a workstation using C ++ and Motif A three level mapping display algorithm is used in the wave viewer Results The algorithm has the characteristics of having a fast display speed and is easily transplanted Conclusion Superiority of the algorithm is fully demonstrated and the rationality of the design of class library approved
