3.1.6. 1030597: Incorrect ETM timestamp value when timestamp and event generation happen on same cycle
Description
When an event packet and timestamp packet are generated on the same cycle, the value of the timestamp packet should be sampled at the time of that event. Because of this erratum, the value of the timestamp is sampled on the previous atom or event packet.
Conditions
- Timestamping is enabled.
- Event packet generation is enabled.
- An event packet and a timestamp packet must be generated on the same cycle.
Impact
The timestamp value might be slightly out of date. In a typical system, atom packets and event packets are frequent relative to the global timestamp signal increment, which means that the amount of errors will be small.
Workaround
There is no workaround for this erratum.
