In this paper, numerical control system design and VHDL modeling are carried out for the production process of printed circuit board PCB based on EDA technology, and the knowledge of electronic design automation is basically understood, and the design process and method of electronic system are initially contacted. By using assembly logic circuit and VHDL language, the realization quality and different design processes and ideas are compared.

Keywords: EDA, digital control of process flow, assembly logic circuit, VHDL modeling
