Abstract
The performance of analog circuits is critically dependent on layout parasitics, but layout has traditionally been a manual and time-consuming task. Recent advances in ML have enabled new capabilities to facilitate fast automated placement and routing. This chapter presents an overview of these techniques, including geometric constraint generation and constrained placement and routing. A variety of ML techniques are used in various steps of analog placement and routing, including graph neural networks, random forest methods, support vector machines, graph attention networks, generative adversarial networks, reinforcement learning, and variational autoencoders. This chapter shows how these general ML algorithms are specifically customized to the requirements of optimized analog layout.
