4.10 Bus Analyzer

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-Xstates 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.
