The Hardware Design of Programmable Logic Device

ABSTRACT

In this paper, firstly introduced the definition of Programmable logic device and the

background of the application in the trainer board and developments at home and

abroad,followed the meaning and content of the subject,as well as chip choices,design software

and programming software.In this design,the EPM7128SLC84-15N series of chips are

used,using Protel 99se design.On the studying boadrd are common function modules ineluding

LED display, seven digital tube,key-stroke input,ete.to help novices rapidly confirm their

studying thought and nurture studying interest. Through the experimental design, to the target

can easily set the development of memory, digital signal processors and special logic functions

such as powerful chips. Design in detail the function of each module that all devices in the circuit

connecting the working methods and approach.Finally, according to design plans of the PCB

board to make experimental circuit board welding.
