Using Symbols
Pattern.
• Use the Find Symbols of Type selections to filter the symbols by type.
4. Select the symbol you want to use from the list of Matching Symbols.
5. If you are using object file symbols, you may need to:
•Set Offset By (see page 162) to compensate for microprocessor
prefetches.
• Set Align to x Byte (see page 163) to trigger on odd-byte boundaries.
6. Select the Beginning, End, or Range of the symbol.
7. Select the OK button.
The name of your symbol now appears as the value of the label.
8. Select the Cancel button to exit the Symbol Selector dialog without
selecting a symbol.
NOTE: When you use symbolic label values in trigger sequences, information about
the symbols is saved with the logic analyzer configuration (and in the trigger
Save/Recall buffer). If you re-compile your program and reload the logic
analyzer configuration (or reload symbols and recall a trigger), the symbol
values are automatically re-calculated.
Triggers set up by the Source Viewer now use symbolic values and are re-
calculated in the same way.

To create an ASCII symbol file
General-purpose ASCII symbol files are created with text editing/
processing tools.
