Why am I getting a "0 items scored" result in my trace report on a MAXDELAY preference?

Whenever "0 items" are shown in a trace report you will need to check to see if that path is covered by another constraint. For example, an INPUT_SETUP constraint has higher priority than a MAXDELAY constraint. Two constraints on the same net will not be calculated, only the highest priority one will, resulting in a "0 items scored" message in the trace report for the other constraint. Check to see if you have more than one constraint on the same path.
