I-Jet Trace A/R/M features
In addition to the above model specifications, I-jet Trace A/R/M has these features:
Support for ETMv3, ETMv4, and PTM/PFT trace and debug interfaces on any Arm
●
Cortex-A/R/M device equipped with CoreSight
Trace port support of up to 350 MHz double data rate (DDR) (700 Msamples/s for
●
each trace data line) for a total of 11.2 Gbit/s throughput
Support for streaming of trace data at up to 3.2 Gbytes/s
●
Automatic alignment of parallel trace data skew on individual bits to compensate
●
for PCB layout and signal integrity problems
Automatic trace data and clock voltage threshold adjustments to get the most
●
reliable trace data collection with noisy or unterminated target boards
64-bit timestamp with 5 ns resolution (or CPU cycle accurate) for precise timing
●
analysis
No external power adapter needed when powering target boards that take less than
●
200 mA
