Technical Support

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 II as trace port analyzer.

The connection to the target is done by standardized adapters defined by manufacturer.

TRACE32 Trace Features

Trace Filter and Trigger

Sample only the specified event
Sample the complete program flow and the specified data event
Switch the sampling to the trace buffer on/off after a specified event occurred

Trace-based Debugging (CTS)

Allows re-debuggging of a traced program section
Provides forward and backward debugging capabilities
High-level language trace display including all local variables
Timing and function nesting display
Has the ability to fill most trace gaps caused by the limited bandwidth of trace port

Trace-based Profiling

Detailed analysis of function run-times
Detailed analysis of task run-times and state
Graphical analysis of variable values over the time
Analysis of the time interval of a single event (e.g. Interrupt)
Analysis of the time interval between 2 defined events

Trace-based Code Coverage

Real-time code coverage without instrumentation
Suitable for long-term testing
Support for all common code coverage metrics
Automated report generation
Full support of multicore chips
