What else needs to be considered with power logic and multi-clock logic.
Traditional low power verification only validates the functional correctness of power control logic, but it does not validate the impact of power logic on multi-clock logic. We will discuss the effects of advanced low power design on CDC design and verification. This paper describes the new CDC issues caused by the addition of power control logic including isolation cells, retention cells, level shifters, and dynamic voltage scaling. It describes the resolution of these CDC issues by employing netlist analysis, assertions and formal verification, and illustrates these issues and solutions with real life Unified Power Format (UPF) examples and designs.

The more compute power, the better. But what’s the best way to get there?
Yield rises with mask protection; multiple sources will likely reduce costs.
More heterogeneous designs and packaging options add challenges across the supply chain, from design to manufacturing and into the field.
CNTs promise big performance improvements, but achieving consistency and replacing incumbent technologies will be difficult.
Computational storage approaches push power and latency tradeoffs.
The backbone of computing architecture for 75 years is being supplanted by more efficient, less general compute architectures.
How long a chip is supposed to function raises questions design teams need to think about, including how much they trust aging models.
Servers today feature one or two x86 chips, or maybe an Arm processor. In 5 or 10 years they will feature many more.
Tradeoffs in AI/ML designs can affect everything from aging to reliability, but not always in predictable ways.
Predicting the power or energy required to run an AI/ML algorithm is a complex task that requires accurate power models, none of which exist today.
New technology could have an impact on NVM, in-memory processing, and neuromorphic computing.
But one size does not fit all, and fine-tuning is required.
Advanced nodes and packaging are turning minor issues into major ones.
