Techniques to find the best hardware configurations (model approaches).
Tradeoff of capacitor size and forward progress~\cite{zhanExploring2022}.
These works do not consider discharge of decoupling capacitor.

Considering sub-normal voltage execution~\cite{zhanExploring2022}.
In transient computing~\cite{balsamoHibernus2015,balsamoHibernus2016,netoDiCA2023,raffeckCO2CoDe2024,reymondEarlyBird2024} (works do not using separate power management system) or hardware-based approaches.
This work shows that considering sub-normal voltage execution is also important for designs using separate energy management system.
They do not address the impact of sub-normal voltage execution to correctness and efficiency of software designs.
