“…It is a standard benchmark taken by all prior methods (Lyu et al 2018;Settaluri et al 2020;Zhao and Zhang 2020;Wang et al 2020;Liu et al 2009). Second, a GaN RF power amplifier (PA) (Diduck et al 2016) whose schematic is not shown here is used as a more challenging high-frequency example. The design space of device parameters and the sampling space of desired specifications for the two circuits are listed in Table 1.…”

The design automation of analog circuits is a longstanding challenge in the integrated circuit field. This paper presents a deep reinforcement learning method to expedite the design of analog circuits at the pre-layout stage, where the goal is to find device parameters to fulfill desired circuit specifications. Our approach is inspired by experienced human designers who rely on domain knowledge of analog circuit design (e.g., circuit topology and couplings between circuit specifications) to tackle the problem. Unlike all prior methods, our method originally incorporates such key domain knowledge into policy learning with a graph-based policy network, thereby best modeling the relations between circuit parameters and design targets. Experimental results on exemplary circuits show it achieves human-level design accuracy (∼99%) with 1.5× efficiency of existing best-performing methods. Our method also shows better generalization ability to unseen specifications and optimality in circuit performance optimization. Moreover, it applies to designing diverse analog circuits across different semiconductor technologies, breaking the limitations of prior ad-hoc methods in designing one particular type of analog circuits with conventional semiconductor technology.
