u cannot get rough power estimation on RTL level if no actual power estimation database related to technology.
but it may help if special power model/simulator with toggle/speed rate from RTL level simulation

   spyglass can do such work in some extent.   it is difficult to get a accurate power estimation in RTL level in my opinion. for some macro level instead of system level, with special power model based on technology, it may help for early power estimation and optimization. it seems to me no general used tool or flow for this point now.
