Analysis and Signoff for Restructuring

For the devices we build today, design and implementation are unavoidably entangled. Design for low-power, test, reuse and optimized layout are no longer possible without taking implementation factors into account in design, and vice-versa. But design teams can’t afford to iterate indefinitely between these phases, so they increasingly adapt design to implementation either by fiat (design components and architecture are constructed to serve a range of implementation needs and implementation must work within those constraints) or through restructuring where design hierarchy is adjusted in a bridging step to best meet the needs of power, test, layout and other factors.
