Quantifying Netlist Interconnect Fault Coverage Using Boundary Scan ATPG Vectors
Quantifying boundary scan interconnect fault coverage pairs extracted netlist node universes with modified counting sequence vector execution logs.
Vector Execution Log
Instruction Trace
Compiled machine code sequences maintain a recorded path of arithmetic operations during the execution phase of a processor or programmable controller. A vector execution log captures the specific sequence of operations performed on vector registers by specialized processing units within an integrated circuit. Such data tracks the exact order of element processing and the alignment of memory access instructions during high speed data throughput.
Engineers monitor this sequence to verify that mathematical operations proceed without hardware stalls or pipeline hazards.
Data Sequence
Diagnostic tools extract these registers to detect discrepancies between intended signal output and measured hardware behavior. The vector execution log documents the state of every SIMD register as the controller processes incoming data streams from peripheral sensors. Differences in the state of the registers identify timing issues or invalid operand inputs that occur during complex matrix multiplication tasks.
Validation logic compares these logs against expected simulation output to confirm that the logic gates within the silicon perform as intended.
Cycle Verification
Logic analyzers produce this audit trail by sampling the state of the internal bus during cycles where vector instructions remain active. This hardware trace confirms that every bit shift or logical operation follows the predefined instruction cycle without unintended memory corruption. The accumulation of these records allows for the identification of intermittent faults that manifest only under peak processing loads.
Analysis of these logs proves the reliability of the underlying hardware architecture.
