Signals compared in CPU Compare Module (CCM)

Arun Ashokan

Hi,

Could you please indicate to me which signals in particular would be compared by the CCM? one document mentioned the words "Output' signals but I would like to know if there are any signals in general are used for the comparison.

Arun,

Most of the CPU interface level signals are compared. Not sure how much of the design information can be shared.

In the meanwhile if you can explain a little more detail on your expectation, we can help you better.

Best Regards,

Karthik.

Karthik,

Thank you for the prompt reply. I needed this information in fact for a customer return. They are analyzing the part and get a CCM-R4 error. They would like to know which signal is throwing an error in order to debug what could be wrong. Would this be possible?

I am also in talks with some colleagues who are helping me thrown some insight on what can be done and what not.

Hi Arun,

There are roughly 1000 signals compared and root cause analysis would require access to the design netlist, ARM RTL source code, and a simulation environment - none of which are available to the end user. As such TI elected not to provide specific identification of miscompared signal.

Best Regards,
Karl
