Lightweight Trace Based Measurement Systems and Methods

摘要

An automotive electronics system includes an electronic control unit and a trace adapter. The electronic control unit is configured to receive measurement signals and provide control signals. Additionally, the electronic control unit is configured to generate or provide trace signals by replacing original instructions in a binary image with trace instructions. The trace instructions are functionally equivalent, but trigger providing the trace signals. The trace adapter is coupled to the electronic control unit. The trace adapter is configured to obtain the trace signals from the electronic control unit.
