Time From Arm Greater Than 41.93 Ms; Waiting For Trigger - HP E2465A PowerPC 604 PGA User Manual

If You Have a Problem
"Time from Arm Greater Than 41.93 ms"
"Time from Arm Greater Than 41.93 ms"
The state/timing analyzers have a counter to keep track of the time from
when an analyzer is armed to when it triggers. The width and clock rate of
this counter allow it to count for up to 41.93 ms before it overflows. Once the
counter has overflowed, the system does not have the data it needs to
calculate the time between module triggers. The system must know this time
to be able to display data from multiple modules on a single screen.
"Waiting for Trigger"
If
a trigger pattern is specified, this message indicates that the specified
trigger pattern has not occurred. Verify that the triggering pattern is
correctly set.
D When analyzing microprocessors that fetch only from word-aligned
addresses, if the trigger condition
is
set to look for an opcode fetch at an
address not corresponding to a word boundary, the trigger will never be
found.
