  • Method and system for functional safety verification
    Patent number: 10267857
    Abstract: A system includes a memory and a processor. The processor is configured to execute computer program codes to perform operations below. A netlist of a functional unit is transformed to a first matrix. The netlist includes information associated with nodes and flip-flops. A first node is selected from the nodes according to the first matrix and a second matrix, to generate a fault list. The second matrix includes weighting values for the nodes. The first node is determined to be associated with a maximum number of the flip-flops. A fault injection is performed on the functional unit. The functional unit is analyzed according to the netlist and the fault list, to generate a first file. A safety mechanism unit is analyzed to generate a second file. A failure is detected according to the first file or a combination of the first file and the second file.
