Title:
CHIP LAYOUT ENCODER TRAINING METHOD AND DEVICE, AND CHIP LAYOUT SCREENING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/066429
Kind Code:
A1
Abstract:
A chip layout encoder training method and device, and a chip layout screening method and device, relating to the technical field of integrated circuits. The chip layout encoder training method comprises: acquiring a sample chip layout and an initial encoder (201); performing geometric transformation on the sample chip layout to obtain at least one reference chip layout (202); extracting sample layout features of the sample chip layout and reference layout features of the reference chip layouts by using the initial encoder (203); and training the initial encoder on the basis of the sample layout features and the reference layout features to obtain a trained encoder (204). By using the methods and the devices, for the chip layouts before and after geometric transformation, a chip layout encoder can output similar layout features, such that the chip layout encoder focuses on extracting a layout feature capable of distinguishing a chip layout type, thereby facilitating subsequent improvement of the accuracy of a clustering result when the chip layout is clustered on the basis of the layout feature.
