MMDS Target Componen t
4.10 Bus Analyzer
4–56 MMDS0508 Target Interface
Use this page to define the search pattern, in the same way you completed the Triggers
page.
The bus analyzer will look at specific collected cycles, match the frame that shows the
pattern, then display this frame in the debugger window.
4.10.5.3.1 Address
In this edit box, specify the Address to be matched.
4.10.5.3.2 Data
In this edit box, specify the Data value to be matched.
4.10.5.3.3 Strobes
Use this area to specify the R/W and LIR-X states to be matched.
4.10.5.3.4 Group A & B Clips
Use these areas’ toggle controls to specify each logic clip as High (H), Low (L) or
Don’t Care (X).
The clips buttons show the Group A and B logic clips with their respective colors.
You use logic clips to trace the signals of your target system as it runs under software
control. When a trigger occurs, a breakpoint shows you the states of significant logic
signals before, at, and after the trigger. Such states can be a search pattern to be
matched.
4.10.5.3.5 Invert
To specify matching any frame without the defined pattern, check the Invert checkbox.
4.10.5.3.6 OK Button
To save your pattern values and close the dialog box, click OK.
4.10.5.3.7 Cancel Button
To close the dialog box without changing any parameter values, click Cancel.
4.10.5.3.8 Next Pattern
To search for the next occurrence of the pattern, choose the Trace>Search>Next
Pattern menu selection. If the search does not find a matching pattern, an error
message reports that fact.
4.10.5.3.9 Previous Pattern
To search for the previous occurrence of the pattern, choose the
Trace>Search>Previous Pattern menu selection. If the search does not find a
matching pattern, an error message reports that fact.
