METHOD AND DEVICE FOR ANALYZING INTEGRATED SYSTEMS FOR CRITICAL SAFETY COMPUTING SYSTEMS IN MOTOR VEHICLES

摘要

The invention concerns a device for analyzing an integrated system (9) comprising at least one CPU card (1), at least one CPU bus (2) and at least one memory (3). Said device comprises a communication module (4) for inputting and editing analysis data using a test interface (5) provided with at least one group of data lines additionally to the control lines. The words containing data and addresses are transmitted alternately or in any succession using the test interface. Thus, it is possible to detect errors while using few CPU card cycles.
