High-speed Serial Trace Interface
Lauterbach is supporting high-speed serial trace interfaces since mid 2008.
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 III / PowerTrace II LITE as trace port analyzer.
The connection to the target is done by standardized adapters defined by manufacturer.
TRACE32 offers a comprehensive trace display and analysis.
TRACE32 offers full access to all NEXUS settings.
|
- BTM, HTM, DTM, OTM, WTM, DQM, PTCM: Selection of Trace method(s).
- TimeStamps: Enable NEXUS client generated timestamps.
- PODT, PTMARK, DTMARK: Special core trace options.
- STALL: Stall cores to prevent overflow of on-chip NEXUS message FIFO.
- Spen<message>: Enable suppression of certain trace messages depending on NEXUS message FIFO fill level.
- PortSize, PortMode: Configuration of Aurora trace port.
- RefClock: Enable reference clock source ofAurora preprocessor.
- CLIENT1/2: Enable and configure additional trace clients, e.g. DMA, FlexRay, SRAM port sniffer.

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.
