This invention relates to a debug device and method thereof and is applied to detect transmission on a bus in a computer system having a CPU, a north bridge chip and a south bridge chip. The debug device consists of a processing unit, a comparing unit and a recording unit. The processing unit receives a first address signal and a second address signal from the north bridge chip, and correspondingly transmits an index signal and a test data to the north bridge chip. The comparing unit compares the first and the second address signal to generate a comparing signal. And the recording unit records the first and the second address signal and the comparing signal. The north bridge chip connects to the south bridge chip via a bus, and the debug device also connects to the south bridge chip. Therefore the north bridge chip and the debug device transmit to both through the south chip.
A debug device for detecting transmission on a bus, coupled to a computer system comprising a CPU, a north bridge chip, a south bridge chip, wherein said north bridge chip and said south bridge chip are connected through said bus, the debug device comprises:
A detection method for detecting transmission on a bus, said computer system comprises a CPU, a north bridge chip and a south bridge chip, wherein said north bridge chip and said south bridge chip are connected through said bus, the detection method comprising:
