This paper describes a simulation-based approach to establish whether a ring-oscillator always converges to the correct mode of operation regardless of its initial conditions and variability conditions. The verification is performed using a predictive global optimization algorithm that looks for a problematic initial state from a discretized state space. The algorithm explores the initial states that...
This paper describes how the difficult problems of designing verifying and testing analog circuits in presence of variability can be converted to easier ones by discretizing the search spaces or discriminating one case from another. For instance discretizing the continuous design space of analog circuits enables the use of an efficient predictive global circuit optimizer. Also discretizing the initial...
