A Debug and Trace Probe with a standard interface to Target Systems (TS) can be used to debug and test both hardware and software components in complex systems. With a debug and trace probe information regarding the operation of the system can be obtained and analyzed to understand how the system is functioning and where problems may lie. This report presents an IEEE 1149.7-compliant cJTAG Controller design and implmentation for use in a Debug and Trace System (DTS).application/pdfen-USIEEE 1149.7cJTAGJTAGIEEE 1149.12013-04-23
