COUNT
The trace depth of the deep analyzer depends on whether or not you installed
memory modules on the analyzer card (refer to Chapter 19, "Installation and
Service", for details). The maximum depth of the 1K analyzer is 1024 states. A
state is a unique combination of address, data, and status values occurring on the
emulation bus simultaneously. When counting is off, the 1K analyzer can store
1024 states in the trace buffer. When counting is on, the 1K analyzer can only store
512 states in the trace buffer. That is because the 1K analyzer must now use two
states in the trace buffer for each state captured on the analyzer bus. One of the two
states stores the state information itself. The other state stores the count information
associated with the state information.
The deep analyzer can always store the same maximum number of states in its state
buffer, regardless of whether counting is turned on or off.
By default, the interface displays a maximum of 256 of states. You can increase the
depth of the trace display buffer to display up to the maximum amount of states that
are available for display. The following command increases the trace display depth
to 512 states:
display trace depth 512
By default, the counting function is turned off in the 1K analyzer, and set to time in
the deep analyzer.
anystate
This option allows you to set up the counting parameter for the analyzer to count
on any state.
off This option turns off trace counting capability. As previously explained, turning off
counting provides a larger trace depth if using the 1K analyzer.
