Abstract

In the paper hazard identification and analysis of CAD and CAT software is performed. The purpose of the analysis is to find the CAD and CAT software modules, the failure of which is potentially dangerous for the future exploitation of the designed with CAD objects, or during the computer aided testing ( CAT) of different devices. On the basis of this analysis on-line and off-line criteria for software safety are suggested. The first can be applied on-line during the functioning of the computer system for detection of dangerous failures and transition to a safe state of the controlled object. The second criterion can be used off-line during the design of the software. The given examples are for electrotechnical systems
