Within the framework of education informatization, a wide range of digital tools is used, among which there are computer modeling tools that allow us not only to study the theoretical foundations, but also to try the knowledge gained in practice. The relevance of the study is determined by the need to use modeling programs for the design and simulation of digital logic circuits for training university students in the field of computer system architecture. This allows the visual representation of digital circuits, creating and testing them in real time, which helps to better understand how logic elements and the more complex models made up of them work. The aim of this study was to examine the effectiveness of using the tool Logisim for developing and simulating digital logic circuits in classes on computing system architecture. An extensive library of logic elements and diagrams is available in it. Logisim allows users to run simulations of their circuits in real time. Users can import and export circuits in a variety of formats, making it easier to collaborate and share projects. The main approaches to the study were the analysis of the works of Russian and foreign researchers related to the use of virtual laboratories for modeling and studying digital circuits of electronic devices, as well as statistical analysis of the results obtained with the use of the Logisim program. In addition, the research materials are based on the experience of teaching computer architecture by the authors. The main results of the study include: description of the functionality of the Logisim digital logic design and modeling tool; demonstration of the stages of design and simulation of digital circuits using it; definition of criteria for assessing the quality of the Logisim program. The results of the study showed that the capabilities of Logisim were highly appreciated by students using it in practical classes on studying the architecture of computing systems. The theoretical significance is represented by the developed criteria for assessing the quality of the software product. The practical significance is determined by the description of the capabilities and the assessment of the quality of the Logisim program: its reliability, the presence of the necessary components and functions for modeling objects of the subject area, as well as accessible and understandable reference documentation are noted.
