man 了一下TIM-107，   TIM-107  (Warning)  The  aggressor  block  net '%s' is not valid and is
       skipped from crosstalk analysis of victim net '%s'

DESCRIPTION
       The victim net is coupled to  an  aggressor  block  net  which  is  not
       present.  This will happen because of dangling connections at the phys-
       ical hierarchy.

WHAT NEXT
       Check the set up for the design.  Check  if  the  design  has  physical
       hierarchy and the net connections are defined properly.
