Abstract: A violation checking method includes generating a violation log report for a design, classifying violation logs in the violation log report into high-risk logs and low-risk logs by a machine learning model, reviewing the high-risk logs, and modifying the design if at least one bug is identified in the high-risk logs.

Abstract: An artificial intelligence (AI)-based constrained random verification (CRV) method for a design under test (DUT) includes: receiving a series of constraints; obtaining a limited constraint range according to the series of constraints; generating a series of stimuli according to the limited constraint range; and verifying the DUT by the series of stimuli; wherein at least one of the step of obtaining the limited constraint range according to the series of constraints and the step of generating the series of stimuli according to the limited constraint range employs an AI algorithm.

Abstract: A system performs the operations of a neural network agent and a circuit simulator for analog circuit sizing. The system receives an input indicating a specification of an analog circuit and design parameters. The system iteratively searches a design space until a circuit size is found to satisfy the specification and the design parameters. In each iteration, the neural network agent calculates measurement estimates for random sample generated in a trust region, which is a portion of the design space. Based on the measurement estimate, the system identifies a candidate size that optimizes a value metric. The circuit simulator receives the candidate size and generates a simulation measurement. The system calculates updates to weights of the neural network agent and the trust region for a next iteration based on, at least in part, the simulation measurement.
