Debugging Use Cases
7
(C) PLS Programmierbare Logik & Systeme GmbH
A trace and debug task can be composed of predefined subtasks
Examples: Observe system components
(program flow, data, signals,…) Initiate actions (enable/disable
trace for code / data /…, count, use timers, use sequencers, etc.)
Bosch GTM Tech Day 2017
Trace based Debugging
Define a trace/debug task
What has to be recorded When it has to be recorded
Run the trace
Analyze the trace result
8
