7.22 Emulation Features and Capability
7.22.1 Advanced Event Triggering (AET)
The C6455 device supports Advanced Event Triggering (AET). This capability can be used to debug
complex problems as well as understand performance characteristics of user applications. AET provides
the following capabilities:
• Hardware Program Breakpoints: specify addresses or address ranges that can generate events such
as halting the processor or triggering the trace capture.
• Data Watchpoints: specify data variable addresses, address ranges, or data values that can generate
events such as halting the processor or triggering the trace capture.
• Counters: count the occurrence of an event or cycles for performance monitoring.
• State Sequencing: allows combinations of hardware program breakpoints and data watchpoints to
precisely generate events for complex sequences.
For more information on AET, see the following documents:
Using Advanced Event Triggering to Find and Fix Intermittent Real-Time Bugs application report (literature
number SPRA753)
Using Advanced Event Triggering to Debug Real-Time Problems in High Speed Embedded
Microprocessor Systems application report (literature number SPRA387)
7.22.2 Trace
The C6455 device supports Trace. Trace is a debug technology that provides a detailed, historical
account of application code execution, timing, and data accesses. Trace collects, compresses, and
exports debug information for analysis. Trace works in real-time and does not impact the execution of the
system.
For more information on board design guidelines for Trace Advanced Emulation, see the Emulation and
Trace Headers Technical Reference Manual (literature number SPRU655).
