2.4.5 In-silicon debug features
The CCI-500 has monitors on all slave and master interfaces that you can use to observe interface status. Each monitor records the number of outstanding read, write, and snoop transactions. It also records the status of the handshake signal from each channel.
This feature can be helpful in the case of a deadlock, for example, the monitors can help to
determine outstanding transactions or where back-pressure is being applied.
The monitors are situated inside the outermost registers of the CCI-500, meaning that the values
indicated are affected by the numbers of pipeline stages configured in a specific
NoteIf the debug registers are accessed through the CCI-500, you might not be able to
read the registers in the case of a deadlock.
