摘　　要：介绍了FPGA器件的基本结构及设计特点,分析了采用FPGA进行电路设计的优势。选用Altera公司的Flex10K系列FPGA器件EPF10K10LC84-4,以交通信号灯控制系统为例,讨论了采用FPGA进行时序逻辑电路设计的思路与方法,使用硬件描述语言VerilogHDL作为输入,给出了核心部分的主要程序代码。最后进行了时序波形的仿真,并对相关波形中出现的毛刺现象进行了相应分析。An introduction of the basic structures and design features of FPGA is provided, and an analysis of the advantages of the circuit design with the application of FPGA is conducted. EPFlOKlOLC84-4 -FPGA parts of an apparatus from Altera company＇ s FlexlOK series are adopted, taking the traffic signal light as an example, the paper discusses the thoughts and approaches to sequential and logical circuit layout by using FPGA, Yerilog HDL-hardware descriptive language is used, at the same time, main procedure codes are released. Finally, emulation of sequential wave form is carried out and phenomena of burrs in wave form are relatively analyzed.
