ELEKTRONINIŲ SCHEMŲ PROJEKTAVIMO PROGRAMOS
PROGRAMS OF ELECTRONIC DESIGN SCHEMES

Summary/Abstract: The article analyses the application of electronic computer design schemes of the Electronics and Engineering study programme in the field of Electronics. Therefore, the advantages and disadvantages of the programs are presented in order to clarify the possibilities of using different computer design programs. Moreover, the computer design programs of electronic circuits are evaluated while performing practical simulation and analysis of electronic schemes in the College of Panevezys. The problem: There are a lot of electronic circuit designing programs. To facilitate the design work, new, specialized, customized one kind electronic product design programs are being developed. The article analyses popular design programs which improve the acquisition of the knowledge of the Electronics subject in the study field of electronics and electrical engineering. The research objective – to analyse the possibilities of using electronic scheme design programs in the process of studies. The research tasks: review the types of electronic scheme design programs and their purpose; evaluate their application possibilities in the teaching of Electronics subject studies. The research methods: scientific literature analysis, research study of electronic scheme design programs and the comparative analysis of the research data. The ready-made documentation can decide upon the purpose, structure and the possibilities of the use of computer design programs of electronic devices. The documents consist of the principal schemes, the results of checking the operation of these schemes and the drawings of the printed circuit boards. Such design results can be achieved by complex design systems. Sophisticated design packages have complex control, require large computer resources and are rather expensive. CircuitMaker is electronic design automation software for printed circuit board designs targeted at the hobby, hacker, and maker community. CircuitMaker is available as freeware, and the hardware designed with it may be used for commercial and non-commercial purposes without limitations. Microsoft Office Visio is a diagramming and vector graphics application and is part of the Microsoft Office family. Microsoft made Visio for Windows available in two editions: Standard and Professional. The Standard and Professional editions share the same interface, but the Professional edition has additional templates for more advanced diagrams and layouts, as well as capabilities intended to make it easy for users to connect their diagrams to data sources and to display their data graphically. MultiSIM is an electronic schematic capture and simulation program which is part of a suite of circuit design programs, along with NI Ultiboard. Multisim is one of the few circuit design programs to employ the original Berkeley SPICE based software simulation. Multisim was originally created by a company named Electronics Workbench, which is now a division of National Instruments. Multisim is widely used in academia and industry for circuits education, electronic schematic design and SPICE simulation. ExpressPCB software is a snap to learn and use. For the first time, designing circuit boards is simple for the beginner and efficient for the professional. Electronic design problems are relevant to a wide circle of users: from the school pupil, vocational or higher school student to the responsible person of the company, the designer of electronic equipment. Having estimated the needs of students how the selection of the elements of electronic circuit diagrams will be done, drawing of schemes or their testing, the research study reviews the programs which are appointed for the studies of Electronics. Studying programs are easy to learn having an unsophisticated data structure, with the possibility to alter the parameters of the elements and inexpensive programs as well. Conclusions Having overviewed the existing electronic scheme design programs according to their purpose, they can be divided into: analog and digital device modelling, functional modelling and printed circuit board design. All design features require different resources, also different databases of the design scheme elements. The research study showed, that to achieve the learning outcomes of the electronics and electrical engineering study subject, the following Circuit Maker, Microsoft Visio, MultiSIM, ExpressPCB design programs are applied. The programs for studies have been selected on the basis of the program database, scheme creation options, testing the operation of the schemes and simulating the design of the scheme. Easy-to-read, user-friendly and inexpensive program is required for the studies of Electronics subject. Therefore, the research study showed that these criteria are in line with the MultiSim program. This program is the most suitable for achieving the learning outcomes.
