4–46 MMDS0508 Target Interface
4.10.3 Collecting Data
When your have initialized the emulator and the bus analyzer have been initialized,
and when you have connected any logic clips that you defined, emulation can begin.
4.10.3.1 Arming the Analyzer
Before you can start data collection, you must arm the bus analyzer. To do so, choose
the MMDS0508>Bus Trace>Arm Analyzer menu selection. The status bar shows
Armed status for the bus state analyzer, and the menu selection changes to Disarm
Analyzer.
4.10.3.2 Disarming the Analyzer
To stop the analyzer, choose the MMDS0508>Bus Trace>Disarm Analyzer menu
selection. The status bar shows Disarmed status for the bus state analyzer, and the
menu selection changes to Arm Analyzer.
4.10.3.3 Start Emulation
To begin emulation, choose the debugger Run>Continue menu selection, or enter any
other command that starts program execution. Emulation continues until a breakpoint,
a watchpoint, the bus analyzer, or you stop the emulation. When emulation stops, the
system updates data in the Bus Analyzer window (see below).
4.10.3.4 Status Bar
The debugger status bar shows the status of the bus analyzer. Before you arm the
analyzer, the status is Disarmed: not ready to collect data. After you arm the analyzer,
the status is Armed: ready to collect data. When emulation begins, the status is
Running: the analyzer is monitoring events. When the analyzer collects data, the status
is Analyzing.
4.10.3.5 Halt Data Collection
To halt data collection manually, choose the MMDS0508>Bus Trace>Disarm
Analyzer menu selection. This stops data collection, but does not stop emulation.
4.10.3.6 Halt Emulation
Stopping emulation also stops data collection, but leaves the analyzer armed. Data
collection resumes when emulation starts again.
