TC11IB
On-Chip Debug Support
The On-Chip Debug Support of the TC11IB consists of four building blocks:
⢠OCDS module in the TriCore CPU
â On-chip breakpoint hardware
â Support of an external break signal
⢠OCDS module in the PCP
â Special DEBUG instruction for program execution tracing
⢠Trace module of the TriCore
â Outputs 16 bits per cycle with pipeline status information, PC bus information, and
breakpoint qualification information
⢠Debugger Interface (Cerberus)
â Provided for debug purposes of emulation tool vendors
â Accessible through a JTAG standard interface with dedicated JTAG port pins
Figure 16 shows a basic block diagram of the building blocks.
