2013.2 Vivado Timing - ERROR: [Constraints-443] set_max_delay -datapath_only: 't1_reg/Q' is not a valid start point

描述

We are applying a set_max_delay constraint and are getting an error as mentioned below.
ERROR: [Constraints-443] set_max_delay -datapath_only: 't1_reg/Q' is not a valid start
Why do we see this issue?

解决方案

The issue is that "Q" is not a valid start point.  Please change the start point to the clock (CLK) pin of that cell or use the cell as the start point.
