The MaxPathsPerTimingConstraint command limits the number of paths reported per timing constraint. For FPGAs, the default is one path per timing constraint. For CPLDs, the default is unlimited. This option can be useful, because it limits the size of report files. By default, the Timing Analyzer reports all paths that satisfy the other settings.
The command is equivalent to the Maximum Paths Per Timing Constraint field in the Report Options dialog box, which is activated by the Options 
Report Options menu command.
The syntax of the MaxPathsPerTimingConstraint command is the following.
MaxPathsPerTimingConstraint number
Number is the maximum number of paths per timing constraint that the Timing Analyzer reports. It is optional. No number turns the limit Off. If number is 0, the Timing Analyzer generates a summary report.
Abbreviate the MaxPathsPerTimingConstraint command syntax as follows.
