A Hybrid Framework for Functional Verification using Reinforcement Learning and Deep Learning

Published: 13 May 2019 Publication History

Abstract

In this paper, we propose a novel hybrid verification framework (HVF) which uses Reinforcement Learning (RL) and Deep Neural Networks (DNNs) to accelerate the verification of complex systems. More precisely, our HVF incorporates RL to generate all possible sequences of vectors needed to approach a target state as well as the corresponding path to the target state which contains a potential design error. Furthermore, HVF utilizes DNNs to accelerate the verification of complex data paths in the target states. We have tested our framework on several circuits including multi-core designs as well as bus-arbiters and confirmed its significant verification speedup when compared to prior work. For example, HVF provides a total speedup of 4.5x for a quad-core MIPS processor verification.
