“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.

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.
