State Compare Menu
Introduction State compare is a software post-processing feature that provides the
ability to do a bit by bit comparison between the acquired state data listing
and a compare data image. You can view the acquired data and the
compare image separately. In addition, there is a separate difference
listing that highlights the bits in the acquired data that do not match the
corresponding bits in the compare image. Each state machine has its own
Compare and Difference listings.
You can use the editing capabilities to modify the compare image.
Masking capabilities are provided for you to specify the bits that you do
not want to compare. "Don’t compare" bits can be specified individually
for a given label and state row, or specified by channel across all state
rows. A range of states can be selected for a comparison. When a range is
selected, only the bits in states on or between the specified boundaries are
compared.
The comparison between the acquired state listing data and the compare
image data is done relative to the trigger points. This means that the two
data records are aligned at the trigger points and then compared bit by bit.
Any bits in the acquired data that do not match the bits in the compare
image are treated as unequal. The don’t compare bits in the compare
image are ignored for the comparison.
When a logic analyzer configuration is saved to or loaded from a disk, any
valid compare data including the data image, etc. is also saved or loaded.
