State The advantages of specifying parameter assignments using defparam are:

- This method always has precedence over specifying parameters at the instance of instantiation.

-  All parameter value override assignments can be grouped inside one module and together in one place, essentially in top-level testbench itself.

-  When multiple defparams for a single parameter are specified, parameter takes value of  the  last  defparam  statement  encountered  in  source  if,  and  only  if,  multiple defparam's  are  in  same  file.  If  there  are  defparam's  in  various files  that override  same parameter, final value of the parameter is indeterminate.
