Analysis Using Listing
Listing is more useful than Waveform when your target system is
running code because it shows the labels as states rather than
transitions. Listing is especially useful when you have defined
meaningful symbol names for your states. If you have an inverse
assembler, you might prefer
Source Viewer
which functions like
Listing.
Example: Examining a Subroutine
Listing is the preferred display tool for state measurements. for
example, if you were trying to see if a subroutine were exiting
abnormally, you might want to measure the number of states between
entering and exiting the subroutine. After acquiring data with the logic
analyzer, you could examine the
data set
in the Listing display like this:
1. Find the start of the subroutine.
Assume the subroutine starts at the address 0x58FC.
a. Select the
Search
tab.
b. Select the down arrow after the Label field, and select
ADDR
.
c. Select the Value field, and enter the starting address, 0x58FC.
d. Select the down arrow after the When field and select
Present
.
e. Select the
Next
or
Prev
button to move the display to the address.
