Abstract
A chip having a debug function includes functional circuitries, a selector circuitry, a data reconstruction circuitry, and a switching circuitry. Each functional circuitry includes a decoder circuit that stores a corresponding set of debug signals and outputs a corresponding debug signal in the corresponding set of debug signals to be a corresponding signal in first signals according to a corresponding address signal in address signals. The selector circuitry selects second signals from the first signals according to the address signals. The data reconstruction circuitry selects first data from the second signals according to split signals and outputs the same to be debug data. Each first data is partial data of a corresponding signal in the second signals. The switching circuitry determines whether to output the debug data or at least one output signal associated with the functional circuitries via output ports according to switching signals.
