14.x - Timing Analyzer - Viewing the Full Clocking Path Under a Period Constraint

Description

In the period analysis we can see the clock skew reported. Is there any switch or setting in ISE which reports the complete clock path in period analysis like in offset analysis?

Solution

The Method to do this is shown below. The steps correspond to numbers in the images. The 'Stopwatch' example design was used here which can be found in:
 
File -> Open Example
 
(1) Double click the icon that looks like a stopwatch, shown below. This will Implement your design and run static Timing.
(2) Now select the .twx tab.
(3) When this tab is selected, you will see Timing appear in the top toolbar. Click Timing and then select Run Analysis.
(4) Change the analyze against field to User Defined Endpoints
(5) Select your endpoints and name your Analysis.
