1. 1. 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

3. 2. Fault Injection for Studying Error Behavior and Validation of Error Detecting Mechanisms

   Författare :Marcus Rimén; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; concurrent error detection; functional error model; control flow error; error detection coverage; permanent faults; data error; error detection latency; simulation-based fault injection; transient faults; physical fault injection; dependability evaluation;

   Sammanfattning : This thesis deals with the design and validation of low-cost error detecting mechanisms that can be used to implement self-checking computers. The research objectives of the thesis are three-fold: (i) to investigate and develop a simulation-based fault injection technique that can be used on a wide range of VHDL simulation models, (ii) to investigate error propagation mechanisms in microprocessors in order to understand how to design low-cost error detecting mechanisms and (iii) to design and validate error detecting mechanisms.

7. 5. On Impact and Tolerance of Data Errors with Varied Duration in Microprocessors

   Författare :Örjan Askerdal; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fault injection; dependability; error propagation analysis; fault tolerance; error effect analysis;

   Sammanfattning : The evolution of high-performance and low-cost microprocessors has led to their almost pervasive usage in embedded systems such as automotive electronics, smart gadgets, communication devices, etc. These mass-market products, when deployed in safety-critical systems, require safe services albeit at low recurring costs.
