What is Tnm_net?
The Timing Name Net (TNM_NET) constraint is essentially equivalent to Timing Name (TNM) on a net except for input pad nets. TNM does not propagate through IBUF or BUFG components. The Timing Name is placed on the input pad. The TNM_NET constraint does propagate through IBUF and global clock buffers.

What are constraints in vivado?
About XDC Constraints XDC constraints have the following properties: They are not simple strings, but are commands that follow the Tcl semantic. They can be interpreted like any other Tcl command by the Vivado Tcl interpreter. They are read in and parsed sequentially the same as other Tcl commands.
