  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. Multiple-Bit Errors in Computer Systems

    Författare :Rolf Johansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fault sim ulation; fault tolerance; single event upsets; error-correcting codes; multiple-bit errors; transient faults; fault modelling; physical fault injection;

    Sammanfattning : This thesis discusses the types of transient faults caused by heavy-ion or a-particle radiation that manifest as multiple-bit errors and how information redundancy techniques can achieve fault tolerance with respect to some classes of multiple-bit errors. The first part of the thesis considers the fault modelling problem, beginning with the problem of how single event upsets (SEUs) originating from faults in register cells in microprocessors manifest as primary errors.
