摘　　要：利用CPLD作为硬件设计平台,在某些芯片对光电转换中的信号进行处理前,对芯片进行初始化配置及其他逻辑控制。仿真显示该方法可以实现所需时序,在顺利通过所设计的测试方案后,最终将相关VHDL代码下载到光电转换板卡中用于实际应用。结果表明,设计完全满足系统要求。Using CPLD as a platform for hardware design, this paper presents two methods of chips configurations before application of signal processing in photoelectric conversion. And the simulation results show that these methods provide a good performance on simulation of time relationship. Through testing, these codes can be downloaded to the photoelectric conversion board in real application. The results show that the design fully satisfies the system requirements.
