针对如何高精度、高速实现模拟前端时序的问题，提出了一种用于平板探测器的模拟前端时序的Verilog实现方法。Verilog语言的编程整体上采用模块化设计，主要包含电荷采集模块、数据读出模块和计数器模块。利用锁相环技术设置各模块不同的时钟信号，通过编写有限状态机和改进型计数器实现各模块的时序。仿真结果表明，该编程方法满足了时序高精度实现的需求，具有运行速度快、灵活性高等特点，达到了预期效果。

Implement of Analog Front end Timing by Verilog

A method of Verilog realization of the analog front end timing used in the flat panel detector is proposed for the implement with high precision and high speed of analog front end timing. Verilog programming uses of modular design including charge collection module, data reading module and counter module on the whole. Each module is set different clock signal by phase locked loop technique, and achieved by writing finite state machine and improved counter. The simulation results show that the method meets the requirements of realizing the timing with high precision, and achieves the desired effect with fast speed and high flexibility.
