Pick to:this paper on technology based on EDA of printed circuit boards PCB production process flow digital control system design and VHDL modeling,a basic understanding of electronic design automation knowledge,preliminary contact with electronic system design processes and methods.And through the use of the assembly logic circuit and VHDL language implementation in two ways,compared the two of realization of quality and different design process and thought.
Key word:EDA,process flow digital control,the assembly logic circuit,VHDL modeling
