Features


Real-Time Trace for StarCore samples all trace data with rates up to 300 Mbit/s per trace channel into the trace buffer.

The trace provides time stamp features and can serve the filter and trigger capabilities of the OCE/EOnce. The system can run on PCs or any workstation.

The connection to the target is compatible to ARM ETM V3.

Trace Modi


Real-Time Trace for StarCore provide full support for all Nexus Trace Port modes except MSEO1 mode.

  • HalfRate: Setup DDR mode to avoid electrical problems of the clock line.
  • MDO8, MDO16, MDO32: Support of all trace port widths of development or production chip.
TOP

Speed


Real-Time Trace for StarCore samples all trace data with rates up to 300 Mbit/s per trace channel. Trace data rates above 150Mbit/s per channel combined with MDO32 require a PowerTrace II device.


More than 100 MHz with trace adapters using AUTOFOCUS self calibration technology.

Basic Nexus 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.
