Due to a problem in the report logic levels script , you may the see the message "inconsistent verticals in report" in the TimeQuest™ Timing Analyzer.
The report logic levels script is available from the Altera website under Support > Support Resources > Design Examples > Design Software > TimeQuest Timing Analyzer
To avoid this problem, change the following line of the tcl script
from
data set [split "[string repeat " " [columns]];“
to
data set [split "[string repeat "; " [columns]];"]
The script is scheduled to be corrected at a future date.
