Research On The Function Development,Test And Teaching Application Of Programmable Logic Device

In the information age,the importance of integrated circuit is self-evident,and the integrated circuit industry is facing a shortage of talents.It is urgent to strengthen the training of talents,and put forward higher requirements for practical teaching in universities.The experimental courses related to chip testing in universities can only test some chips with simple pins,and it is difficult to obtain multi pins specific chips.Students' chip testing ability can not be effectively trained.Programmable logic devices can be developed according to users' needs.After configuration,they can be used as multi pins specific chips for testing research.At the same time,the current programmable logic device experiment has the problem that the development board is easily restricted by the established resources and can not give full play to students' creativity.Therefore,it is of great significance to study and improve the chip practical courses in universities in order to improve the teaching effect.Based on the demand of teaching application,this paper studies and integrates the current programmable logic device development experimental courses and chip test experimental courses,and explores the teaching application of chip test virtual simulation system.Firstly,the basic logic gate function and home environment monitoring function are developed based on the programmable logic device,and the waveform simulation is carried out;secondly,the multi pins chip test equipment is studied,and the test of programmable logic device is completed;thirdly,in view of the limited number of chip test equipment and the limitation of students' time arrangement,a virtual simulation system for chip testing is developed;finally,the above work is successfully applied to practical teaching.Through the research on the function development and test of programmable logic devices,this paper improves the related experimental courses in universities.Students can flexibly develop the function of programmable devices,fully exercise the ability of circuit development,and get familiar with the test process and principle in advance by using the chip test virtual simulation system,which saves a lot of time for the practical operation of equipment,greatly speeds up the experimental speed,so as to improve the teaching effect.
