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
memory 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.
