2-10 Using the Analyzer
Assigning Values to the Range Resource
The range resource defines a range of values associated with a
particular trace label. Move the cursor to the range label field and use
the Tab key to view the predefined trace labels. Notice that these
labels are also used when assigning values to the pattern resources.
Trace labels are described in the "Assigning Values to the Pattern
Resources" section that follows.
Pressing the right arrow key moves the cursor to the starting value
field. Notice that you are given a line in the bottom part of the display
in which to enter the value. The value you enter on this line may be
longer than the space available in the starting value field; when this
happens, as much of the value as possible is shown in the starting value
field. Pressing the right arrow key again moves the cursor to the
ending value field.
Assigning Values to the Pattern Resources
You can assign address, data, status, and xbits (if an external analyzer
is present) values to each of the pattern resources.
Move the cursor to the field to the immediate right of a pattern resource
and press the Tab key a couple times. When "=" is selected, the
pattern is equal to the state described by the following values; when
"!=" is selected, the pattern is not equal to the state described.
The addr, data, stat, and xbits (if an external analyzer is present)
columns allow you to assign values to each of the trace labels. When a
pattern has values assigned to more than one trace label, these values
are ANDed. In other words, if you assign an address value of 500H and
a data value of 1234H to a pattern, a captured state must have an
address of 5FFH AND data equal to 1234H in order to match the
pattern.
Trace Labels. The following trace labels are predefined in most of
the HP 64700 Series emulators:
addr
Represents the trace signals which monitor the
emulation processor's address pins (trace signals 0
through 23 in the 68000 emulator).
