Extracting Records from the Acquired Information

Use the filtering function to extract the records you need from the acquired trace information. The
filtering function allows the trace information acquired by hardware to be filtered by software.
Unlike the settings made in the [Trace Acquisition] dialog box for acquiring trace information by
conditions, changing the settings for filtering several times to filter the acquired trace information
allows easy extraction of necessary information, which is useful for analysis of data. The content
of the trace buffer will not be changed even when the filtering function is used. Acquiring useful
information as much as possible by the [Trace Acquisition] settings improves the efficiency in
analysis of data because the capacity of the trace buffer is limited.
Use the filtering function in the [Trace Filter] dialog box. To open the [Trace Filter] dialog box,
select [Filter...] from the popup menu.
The [Trace Filter] dialog box has the following pages:
Table 5.5 [Trace Filter] Dialog Box Pages
Page
[General]
[Address]
[Data]
[Type]
[Bus]
[R/W]
Note: Items other than [General] and [Address] vary according to the emulator in use. For details,
refer to the online help.
Set filtering conditions and then press the [OK] button. This starts filtering according to the
conditions. Clicking the [Cancel] button closes the [Trace Filter] dialog box, which holds the
settings at the time when the dialog box was opened.
In filtering, only the trace information that satisfies one or more filtering conditions set in the
above pages will be displayed in the [Trace] window.
