应用TEXTIO和MATLAB进行复杂数字系统仿真

Application of TEXTIO and MATLAB in simulation of complicated digital system

在基于FPGA的复杂数字系统的仿真测试中,设计者常常面临各种挑战。以数字图像处理系统的仿真为例,如果采用完备性仿真测试方法,那么测试矢量的数量将是非常巨大的;如果采用常规方法,不仅效率不高,而且可能无法达到仿真测试的目的。针对这个难题,提出一种进行仿真测试的新方法,该方法应用TEXTIO和MATLAB来辅助仿真测试过程,使问题得到较好的解决。以电视图像实时多目标捕获单元的仿真测试为例,全面、细致地讨论这种新方法。

While coping with an FPGA-based simulation of complicated digital system,the designers usually face the challenge of explosion of test vectors.For example,to an FPGA-based simulation of digital image process system,if the designers adopt a complete test method,then the quantity of test vectors will be prohibitedly huge; if the designers adopt other popular methods, not only the efficiency is low, but also it may be infeasible. Aiming at this problem, a new method of simulation test which applies the TEXTIO and MATLAB tools to simulation test process is provided,making the problem resolved more elegantly. As an example, the method by means of the simulation test process of realtime multi-target capture unit for television video is discussed.
