基于VHDL的生产线定时计数系统设计

Design of Timing and Count System of Production Line based on VHDL

定时计数系统在自动化生产线中有着广泛的用途。本文采用VHDL硬件描述语言,运用自顶向下的设计思想设计了生产线中定时计数系统。文中给出了系统硬件连接图、总体逻辑结构图并进行了逻辑仿真。结果表明,该定时计数系统设计功能正确,结构简单、控制精确。

The timing and count system is an important part of automatic production line.In this paper,the design of timing and count system of production line based on VHDL（Very high speed IC Hardware Description Language） by the top-down method was put forward.The hardware diagram,logic design of the system,and logic simulation were described in detail.The results show that the whole designed system based on VHDL has the advantages of accurate functions,simple structure,and good flexibility.
