Abstract

The article provides examples of the use of programmable logic integrated circuits in various industries. Possible faults in FPGA blocks and their difference from faults in programmable logic arrays are described. Particular attention is paid to the failures of the LUT element. Features of the organization of technical diagnostics systems operating in the operating mode of the objects of diagnostics for combinational logic devices, implemented on the basis of programmable logic integrated circuits are described. Using the example of modular summation codes, it is shown that the known approaches to organizing such systems for devices implemented on a valve basis can be directly applied to devices of the type under consideration. Since malfunctions in the form of errors are recorded, and not the malfunctions themselves, the approaches to the organization of diagnostic systems are universal. It also provides a comparative characteristic of modular sum codes depending on the code module. A code has been proposed that will detect all faults in the example under study.
