TARGET DEVICE PROVIDING DEBUGGING FUNCTION AND TEST SYSTEM COMPRISING THE SAME

摘要

A test system for debugging a target device includes a switch unit configured to transfer a test signal to the target device, the target device including a first intellectual property (IP) block supporting a debugging operation at a normal mode and a second IP block supporting a debugging operation at a power saving mode. The switch unit is configured to form a first signal transfer path for transferring the test signal to the first IP block at the normal mode and to form a second signal transfer path for transferring the test signal to the second IP block at the power saving mode.
