14.x Timing Analyzer - How to report paths by constraint?

Description

I am trying to produce a timing report, but the default timing analyzer reports paths bythree endpoints per constraint.

How can I modify the options so that it reports paths only by constraint?

Solution

In "Post-Place & Route Static Timing Report Properties",

-n (Report Paths Per Endpoint)
This option reports paths per endpoint

Please set "Report Paths by Endpoint (-n)" to 0. Thispreventspaths from beingdisplayed by endpoint.
Then, you can set "Number of Paths in Error/Verbose Report" to the number of your interest.

For example, with -v 3000 and -n 0, you will see 3000 worst case paths for each constraint.
The higher the limit value, the longer it takes to generate the timing report.
