Abstract

We present Duplex random tree search, an algorithm to optimize performance metrics of analog and mixed signal circuits. Duplex determines the optimal design, the Pareto set, and the sensitivity of a circuit’s performance metrics to its parameters. We demonstrate that Duplex is 5x faster than the state-of-the-art and finds the global optimum for a design whose previously published result was a local optimum. We show our algorithm’s scalability by optimizing a system-level post-layout charged-pump PLL circuit.
