摘要
CCD作为一种应用广泛的新型半导体光电器件，驱动时序电路的实现是其应用的关键问题，运用VHDL硬件描述语言，结合复杂可编程逻辑器件CPLD，完成了对CCD的驱动时序电路的设计，给出了部分VHDL语言源代码，利用MAX+plusⅡ软件实现了时序仿真，讨论了VHDL语言设计中的一些问题。
CCD is a new semiconductor photoelectric device widely used in some fields. The design of the time sequence driving circuit of CCD is a crucial problem of its application. VHDL and CPLD are used together to complete the design of the time sequence driving circuit of CCD. Some of the codes with VHDL are given. Timing simulation of circuit running on MAX ＋ plus Ⅱ is presented. Some problems of VHDL design are analyzed and studied.
