  • System on chip including built-in self test circuit and built-in self test method thereof
    Patent number: 9575861
    Abstract: A system on chip is provided which performs a built-in self-test operation using an error access pattern. The system on chip includes a master device and a slave device. A bus is configured to transfer an instruction from the master device to the slave device. A built-in instruction capture circuit is configured to receive and store the instruction. The built-in instruction capture circuit stores the instruction as the error access pattern when an error occurs in the slave device due to the instruction.
    Type: Grant
