Example State Overview example
An example of a State Overview measurement is testing for access to a
reserved area of memory. In this case, the address bus of the target
system would need to be grouped under a single label, such as ADDR.
By selecting the ADDR label in State Overview mode, and by defining
the full range of the label (Low value = 0000, High value = FFFF with a
16-bit ADDR label), activity over the entire address range can be
monitored. Access into reserved mem ory is easily identified.
By selecting only the range of the reserved area of memory with the
Low and High values, the number of address values per bucket is
decreased and a more detailed analysis can be performed.
The figure below shows a State Overview display.
