  • Integrated circuit with scan-based debugging and debugging method thereof
    Patent number: 7533315
    Abstract: An integrated circuit comprises a test interface, an embedded in-circuit emulator, a circuit-under-debugging, and a memory. The embedded in-circuit emulator is used for software debugging via the test interface. The circuit-under-debugging comprises a scan chain dumping states of every delayed flip-flop (DFF) out of the circuit-under-debugging. The memory stores the states from the scan chain and transfers the states to a computer via the test interface.
    Type: Grant
