The evolution of hardware design is analogous to the evolution of software, but is years behind. Well "So What?": It is not that RTL is bad because the gcc compiler translates to "RTL" as an intermediate step, then the back end converts to specific instruction sets for each different cpu. We need to look at what really has to happen when designing a system and draw on the analogies.
Things like reuse, encapsulation, abstraction, etc, exist in OOP. There are also data flow and control/decision functions. HDL modules can be modeled by OOP classes(control and data flow) then compiled and instantiated to run with the application being developed, rather than being run on an "RTL" simulator.
The point is to capture the function and integrate it with the software without using
antiquated technology. The compilation will also be much faster because the routing and placement associated with HDL is unnecessary.
