Why use SAW?
• Symbian OS specific
… Process and threads
… Exes, DLLs and functions
… Memory models
• Based on Symbian’s Unified Trace Framework
… Symbian OS and custom trace events
• Integrated analysis tools
… CPU profiler, Memory analysis, Trace viewer, Thread Sync
• Extensible framework
… Demand paging (Q1/2009)

Tracing, how does it work?
Software tracing
… Add trace points into the source code
… Runs on both hardware and emulator
… Is intrusive
Unified Trace Framework (UTF)
… Runtime and build-time controlled
… Generates compact binary output on the target
Consumed by SAW
… Allows custom tracing
