The road to optimized tradeoff automation is long. Changing attributes along the way can make it even more difficult.
Complexity challenges long-held assumptions. In the past, the semiconductor industry thought it understood performance/area tradeoffs, but over time it became clear this is not so simple. Measuring performance is no longer an absolute. Power has many dimensions including peak, average, total energy and heat, and power and function are tied together.
Design teams are now dealing with the implication of safety and security, which have considerable impact on power/performance/area (PPA) considerations. We are far from understanding the tradeoffs ….
