Diagnosis Infrastructure of Software-Hardware Systems
(EWDTS, 2011) Yves T.; Hahanov, V.; Alnahhal O.; Maksimov, M.; Shcherbin, D.; Yudin, D.
This article describes an infrastructure and technologies for diagnosis. A transactional graph model and method for diagnosis of digital system-on-chip are developed. They are focused to considerable decrease the time of fault detection and memory for storage of diagnosis matrix by means of forming ternary relations in the form of test, monitor, and functional component. The following problems are solved: creation of digital system model in the form of transaction graph and multitree of fault detection tables, as well as ternary matrices for activating functional components in tests, relative to the selected set of monitors; development of a method for analyzing the activation matrix to detect the faults with given depth and synthesizing logic functions for subsequent embedded hardware fault diagnosing.
