An integrated circuit die has a peripheral edge and a seal ring extending along the peripheral edge and surrounding a functional integrated circuit area. A test logic circuit located within the functional integrated circuit area generates a serial input data signal for application to a first end of a sensing conductive wire line extending around the seal ring between the seal ring and the peripheral edge of the integrated circuit die. Propagation of the serial input data signal along the sensing conductive wire line produces a serial output data signal at a second end of the sensing conductive wire line. The test logic circuit compares data patterns of the serial input data signal and serial output data signal to detect damage at the peripheral edge of the integrated circuit die.
