在电子设计领域,随着计算机技术、大规模集成电路技术、EDA(Electronics Design Automation)技术的发展和可编程逻辑器件的广泛应用,传统的自下而上的数字电路设计方法、工具、器件已远远落后于当今技术的发展。基于EDA技术和硬件描述语言的自上而下的设计技术正在承担起越来越多的数字系统设计任务。本文首先综述了EDA技术的发展概况,FPGA/CPLD开发的流程、优点,VHDL语言的历史、开发步骤及其优点;然后介绍了频率测量的一般原理;接着使用EDA技术,用VHDL语言完成了数字频率计系统的设计工作;最后介绍了EDA技术的前沿发展趋势及系统开发的几点体会。
本课题的数字频率计设计,完全使用一块复杂可编程逻辑器件CPLD(Complex Programmable Logic Device)芯片EPM7128SLC84-15实现整个电路的测试信号控制、各种时序逻辑控制、计数功能、数码管的显示输出。在MAX+PLUSII、QUARTUS软件平台上,用VHDL语言编程完成了CPLD的软件设计、编译、调试、仿真和下载。不但大大缩短了开发研制周期,而且使本系统具有结构紧凑、体积小、可靠性高、测频范围宽、精度高等优点。本文详细论述了系统自上而下的设计方法及各部分硬件电路组成及CPLD的软件编程设计。

Design the field in the electron, with computer technology, large scale integrated circuit technology, EDA (Electronics Design Automation) Development of technology and wide application of programmable logic device, the traditional digital circuit design method, tool, device from bottom to top have already far lagged behind development of current technology. The designing technique from top to bottom based on that EDA technology and hardware describe the language is bearing more and more digital systems and designing the task. The development overview of the survey EDA technology at first of this text, procedure, advantage that FPGA/CPLD develops, history, development step and advantage of VHDL language; Then introduced the general principle of frequency measurement; Then use EDA technology, finish the systematic design work of the digital cymometer in VHDL language; Some experience of introducing front development trend and system of EDA technology finally and developing.
