To specify a label pattern event (Timing only)
Label pattern events let you specify patterns or ranges on a bus.
1. Select the label name button and choose the label that you want to look for
a pattern on.
You can also insert other label events if you want to look for multiple
patterns on multiple labels. Once another label event is inserted, you can
choose And if both label events must occur in the same sample or Or if
only one of the label events must occur.
2. Select the operator button and choose the appropriate operator.
The In range and Not in range operators consider the values you enter to
be inside the range. Ranges and inequalities cannot be set on labels whose
bits have been reordered.
3. Select the number base button, and choose the number base that you
want.
If the number base is changed in one window, the number base in other
windows may not change accordingly. For example, the number base
assigned to symbols is unique, as is the number base assigned in the
Listing window.
4. Enter the label value.
Xs mean you don't care about the value on the specified bits. Xs are not
allowed in ranges or inequalities.
If you chose the Symbols or Line #s number base, select the Absolute
XXXX button, and use the Symbol Selector dialog to choose the symbol or
line number value.
