Example
An example of a State Overview measurement is testing for access to a
reserved area of memory. In this case, the channels of 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.
The figure below shows a State Overview display.
