Specious argument.'View' may be "better" than 'architecture', but the
use of 'architecture' for specifying different representations of VHDL's
equivalent of modules is already accepted usage. Using 'view' in Verilog
instead of 'architecture' is just "being different for the sake of being
different".
I would also argue the opposite of yourself, on the grounds that
'architecture' has to do with 'building' the circuit (elaboration &
configuration), and 'view' seems perfectly applicable when both 'digital'
and 'analog' values are present for the same signal.
Also if 'view' or 'architecture' is to be a new keyword, I'll bet there
will be fewer problems with 'architecture'.
