High-speed Serial Trace Interface |
Lauterbach is supporting high-speed serial trace interfaces since mid 2008. They started with ARM-HSSTP followed by serial traces for the QorIQ and PPC400 architecture.
Parallel trace data is coded 8b/10B and converted to a bit stream by the target device. This bit stream is sent via differential lanes to the TRACE32 preprocessor which recovers the original parallel data.
The max. supported speed for the serial trace interface depends on the number of data lanes.
- 6.250 Gbit/s per lane (up to three lanes)
- 3.125 Gbit/s per lane (at four lanes)
High-speed serial trace interfaces require PowerTrace II as trace port analyzer.
The connection to the target is done by standardized adapters defined by manufacturer.

Trace Display |
TRACE32 offers a comprehensive trace display and analysis.
|
NEXUS Settings |
TRACE32 offers full access to all NEXUS settings.
|
- BTM, OTM, WTM, DQM: Selection of Trace method(s).
- TimeStamps: Enable core timestamp for core trace messages.
- PODT, PTMARK,DBFCMSK: Special core trace options.
- STALL: Stall cores to prevent overflow of on-chip NEXUS message FIFO.
- Spen<trace method>: Enable suppression of certain trace messages depending on NEXUS message FIFO fill level.
- PortSize: Set amount of high speed serial lanes used for tracing.
- PortMode: Set transfer speed of high speed serial lanes.

Basic Filter and Trigger |
The basic filter and trigger features are easy to use.
|
- TraceEnable: Sample only the specified event.
- TraceData: Sample the complete program flow and the specified data event.
- TraceON: Switch the sampling to the trace buffer on after the specified event occurred.
- TraceOFF: Switch the sampling to the trace buffer off after the specified event occurred.
- TraceTrigger: Stop the sampling to the trace buffer at the specified event. A trigger delay is possible.
