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.
