Self-Calibration

Lauterbach′s TRACE32 software provides a push-button-solution for optimal hardware configuration including a trace port test. Just push the AutoFocus button and a small test programm is downloaded to the target causing worst case test patterns on the trace port. Trace probes with AUTOFOCUS are capable of recognizing data eyes, adjusting reference voltage such that clocks are stable and data channels have broad data eyes. Last not least optimal sampling points are calculated and setup for every data channel.

AUTOFOCUS Self Calibration

Successfully deployed for trace port data rates in excess of 600 Mbit/s per trace channel
Up to 40 trace channels
Up to 16 Gbit/s total bandwidth
Data eye recognition capability
78 ps time resolution
Automatic adjustment of termination voltage
Automatic adjustment of threshold voltage separately for all clock and data channels
Automatic adjustment of clock delay
Automatic adjustment of data delay for every single channel
Automatic trace port test

Software

The PowerTrace samples all trace port lines up to a speed of 500 MHz into the trace buffer. The maximum size of the trace buffer is 64/128 MFrames (1 frame per clock).

The connection to the target is done by standardized adapters defined by manufacturer. The system can run on PCs or any workstation.
