what happens to logic after synthesis which is driving an unconnected output port that is left open that is noconnect during its module
the disadvantages of specifying parameter assignments using defparam are- parameter is essentially specified by the scope
state the advantages of specifying parameter assignments using defparam are- this method always has precedence over specifying parameters at the
the disadvantage of specifying parameter during instantiation are- this has a lower precedence when compared to assigning using
the advantages of specifying parameters during instantiation method are- all values to all the parameters do not need to be specified only those
using module-instance parameter parameter values can be overridden while a module is instantiated new parameter values are passed at the time of
