SEMICONDUCTOR DEVICE WITH DEBUGGING FUNCTION, SEMICONDUCTOR OPERATION MONITORING SYSTEM, AND DEBUGGING SIGNAL OUTPUT METHOD

摘要

The device is provided with at least one functional block, multiple connection terminals that include an output bus terminal used solely for signal output, an acquisition unit for acquiring an internal signal that shows the operation status of at least one functional block and that is obtained using debugging function, and an output conversion unit to which are input a normal signal output to the output bus terminal and the internal signal, and that generates a debugging signal by superimposing the internal signal on the normal signal and outputs it to the output bus terminal.
