Open publisher page 0 citations

Abstract

The hierarchy design method of digital system based on EDA is proposed through the design of digital frequency meter system in this paper. Firstly, it divides the frequency meter into different function module and Writes VHDL code to describe each module circuit. Then, it creates the schematic diagram of top circuit. Design input, compiled, logic synthesize and function simulation are accomplished use MAX+PLUS II. In the end, digital frequency meter is implemented in CPLD. The results show that the design method can greatly simplify the complexity of hardware circuit structure. Its characteristic is high reliability and strong flexibility.
