An apparatus and method for selecting and outputting test patterns and internal signals during various SHBI modes of operation. The apparatus may include multiple input/output (I/O) pins, one or more functional blocks, a Self-Heat Burn-In (SHBI) state machine that is coupled to the I/O pins and the one or more functional blocks, and a logic selector circuitry that is coupled to the SHBI state machine and the one or more functional blocks. The SHBI state machine may provide to the I/O pins with first one or more test patterns during a first SHBI mode of operation, and to provide the one or more functional blocks with second one or more test patterns during a second SHBI mode of operation. The logic selector circuitry is configured to select and output the first one or more test patterns to stress the I/O pins during the first SHBI mode of operation, and to select and output internal signals of the one more functional blocks during the second SHBI mode of operation.
