When designing digital systems, the stages of design debugging are important and laborious. Debugging is carried out on the manufactured prototype of the digital system. For debugging, in addition to the object being debugged, a set of debugging tests and the ability to organize debug modes on the system prototype are required, which allow, by analyzing intermediate variables, to localize an error in the project when an incorrect reaction of the system prototype to a debug test is detected. The advantages and disadvantages of design debugging on the hardware prototype of the entire digital system are considered, as well as the method for selecting a typical standard core. In the latter case, only prototypes of atypical interface circuits and blocks are made, which are connected to a previously manufactured and debugged standard core. The features of both approaches are analyzed. Classes of the most frequent applications of the considered methods are formulated.
