Used in that sense, the same software could be called Samsung's and Intel's and any other foundry's, since it is qualified for use with those processes as well. But that's not really the main point I was making, which was that there have been 20+ years of cooperative effort in both process design and EDA software to optimize for power and trade it off against other optimization goals. While there are design and packaging approaches that are only coming into use because of "end of Moore's law, what do we do now" reactions, and some may have power implications, power optimization predates that by a good while.
