   Författare :Peter Folkesson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fault tolerance; concurrent error detection; dependability; coverage; fault injection; experimental validation; boundary scan;

   Sammanfattning : This thesis deals with the problem of validating and estimating the effectiveness of error handling mechanisms in computer systems. The main contribution is an assessment of the effectiveness and usefulness of several physical fault injection techniques. LÄS MER

5. 4. Switch-Level Fault Simulation Based on Local Algorithms

   Författare :Peter Dahlgren; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; switch level; fault propagation; fault simulation; physical fault injection; short faults; stuck-at faults; fault modeling; transients; self-checking circuits; multiple dominance;

   Sammanfattning : The presence of realistic faults in CMOS networks, such as shorts and opens, frequently gives rise to intermediate voltage values. At the switch level, these values result in undetermined logic states (X) which are likely to propagate to the outputs, causing uncertainty in the estimation of test set efficiency. LÄS MER

7. 5. On Fault Injection-Based Assessment of Safety-Critical Systems

   Författare :Daniel Skarin; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transient Faults; Fault Injection; Error Detection and Recovery; Fault Tolerance; Embedded Control Systems;

   Sammanfattning : This thesis deals with techniques for designing and evaluating error detection and recovery mechanisms for computer systems. For the assessment of such systems, we describe a comprehensive fault injection tool that is capable of emulating the effects of hardware errors in microprocessors. LÄS MER
