摘要:The awareness of the ideas about the work of modern computers is important for the future IT specialists’ preparation. Processes occurring in the middle of the computing system are based on the work of the physical devices,the modeling of which is advisable to carry out in simulation software. The authors consider the problem of choosing simulation software of physical processes. The experience of teaching microelectronics course allowed to choose two simulation software:Proteus and Multisim. The pedagogical experiment on the choice of the optimal simulation software to support the course of microelectronics,which is studied by future ITspecialists and computer science teachers,was conducted based on Makarenko Sumy State Pedagogical University (Ukraine). The comparative analysis of the individual characteristics of the simulation software prefers Proteus. However,the results of the pedagogical experiment confirm the feasibility of attracting Multisim.
