The increasing complexity of microchips and the limitations of miniaturisation are making the electronics design process more complex and time-consuming. The problem of Moore’s Law losing its force is causing rapid development in the design and manufacture of electronic components. The study aimed to provide structured information on electrical circuit design tools by functionality and availability to help optimise operations, increase productivity and save money. The study provided a theoretical description of the principles of operation of software for modelling and simulation of electrical circuits, an overview of algorithms and methods used in automatic design programs, a classification of programs by key characteristics and a comparative analysis of popular software packages: LTspice, EAGLE, MATLAB/Simulink, Multisim, Proteus, KiCad. The analysis addressed the speed of modelling, accuracy of results, ease of use, functionality and accessibility, as well as user experience. The study recommended selecting software depending on the user’s needs, project complexity and budget, accounting for the experience of other users. LTspice, Multisim, and KiCad were recommended for beginners and students: LTspice is powerful, free and easy to use, KiCad offers open source and an active community, and Multisim is suitable for learning. MATLAB/Simulink, Proteus and EAGLE are recommended for professionals: Simulink provides powerful modelling and integration with other MathWorks products; Proteus is optimal for microcontroller system developers; EAGLE is suitable for integration with CAD and automation systems. The practical value of the research results lies in the creation of a rating of EDA software by the criteria of functionality and performance, designed to help users make a choice based on their needs
