摘　　要：针对数字信号处理器的不同仿真测试要求,提出了基于软硬件协同仿真平台的功能仿真测试方法。采用软硬件协同仿真测试的方法,提高了被测处理器的仿真测试速度;采用基于指令模型的指令集测试程序,提高了基本指令集的测试覆盖率;采用基于流水控制单元状态机变换路径的测试程序,提高了指令间数据竞争的检测。实验结果表明,指令的覆盖率达到了100%,且DSP处理器代码的覆盖率也达到了满意的程度。To satisfy different requirement of simulation and testing for digital signal processor, a functional simulation and testing method are proposed. Using the method of Software/Hardware Co-simulation, the speed of simulation and testing is raised. Testing coverage rate of instruction is highly improved by testing program of instruction based-on model of instruction Using pipeline control based simulation model, data hazard between instructions is detected. Experiments show that instruction coverage achieves 100 percent, and also code coverage of DSP is satisfied with the specification.
