Annotation: In modern projects to create digital computer devices, programmable logic integrated circuits are widely used. To solve problems based on them, a necessary condition is the use of programmers. Different integrated circuit manufacturers usually use their own designs, which are often difficult to access. The paper presents a methodology for creating a universal programmer that meets the requirements of several manufacturers simultaneously. A special feature of the solution is the use of a JTAG interface as part of the programmer, which allows it to be used for debugging and testing the main blocks of the device being developed. The capabilities of the JTAG boundary scan technology for this class of devices have been studied. A version of the universal programmer model has been developed for use with FPGAs from various manufacturers. The results are confirmed by experimental studies carried out on real equipment. The practical stages of the project are shown, the quantitative values of the parameters are determined. Recommendations have been developed along the entire route of designing a digital device in a computer-aided design system to enable the complete development and production of a functional product in production. A method for conducting an experiment using a prototype of a universal programmer is proposed. The results of experimental studies confirmed the correctness of the chosen solution.
