摘　　要：在基于FPGA的复杂数字系统仿真测试中,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;而如果采用常规方法,则不仅效率不高,甚至可能无法达到仿真测试的目的。针对这个难题,讨论了一种进行仿真测试的新方法,该方法应用TEXTIO和M atlab来辅助仿真测试过程,使问题得到较好地解决。并且以电视图像实时多目标捕获单元的仿真测试为例,对这个新方法给予全面、细致地讨论。While coping with an FPGA - Based simulation of complicated digital system, we usually face the challenge of explosion of test vectors. For example, to an FPGA - Based simulation of digital image process system, if we adopt a complete test method, the quantity of test vectors will be prohibitedly huge ; If we adopt other popular methods, not only the efficiency is low, but also they may be infeasible. Aiming at this problem, this paper discusses a new method of simulation test, which applies the TEXTIO and Matlab tools to simulation test process, makes the problem resolved more elegantly. As an example, this paper expounds the method by means of the simulation test process of Real - time Multi - target capture Unit for television video.
