Abstract

The use of simulation laboratories is gaining popularity in thedomains of engineering programs. However, the experience in teaching showsthat the simulation itself is not very effective in didactic processes. Teachingprocesses in thefield of specialist subjects, designed for students of technicaluniversities, should be based on direct operations performed by the student onreal devices. At the same time, at the later stages of didactic processes, moderncomputer tools and techniques that enable modeling, simulations and mea-surements of projected systems or devices cannot be omitted. The article pre-sents an example of applications of computer technology in the analysis ofsystem properties at the stage of their designing, commissioning and testing ofprototype properties. Based on the chosen hybrid system, in mixed analog-digital technology, the novel techniques of testing its functional properties werepresented. The multiplatform combined with graphical programming and sim-ulation software and hardware allows comparing a schematically captured cir-cuit with a prototype of the same design. The platform based on NI myDAQinstruments and the Multisim Circuit Design software is presented. To illustrateits capabilities, the generator of the sawtooth wave with a mixed analogue-digital structure was tested. The integration between NI Multisim and NImyDAQ makes possible to correlate real and simulated measurements in asingle interface. The possibility of presented techniques combined use allowsoptimizing the processes of designing, commissioning, testing and teaching theproperties of electronic circuits.
