The increasing complexity of modern electronic devices driven by consumer demand and technological advancements presents significant challenges for designers. The reduced feature size and increased capabilities lead to more complex designs as more sub-systems are packed into a single chip. Traditional synthesis and optimization methods which involve CAD tools for accurate simulation are computationally...
Speeding up the design optimization process of Analog/Mixed-Signal circuits has been a subject of active research. Techniques such as metamodeling, artificial neural networks, and optimization over SPICE netlists have been used. While the results are accurate and promising, the effects of process variation on design space exploration still persist. Metamodels created by existing techniques are still...
As the complexity of mixed-signal systems grows, the challenges of their design becomes exponentially more difficult. In order to mitigate this problem, this paper proposes a two stage approach that uses accurate metamodels and efficient algorithms for fast mixed-signal system optimization. The different components of a Phase-Locked Loop (PLL) are considered as case study. First, the metamodel creation...
