API Reference

LAYout with Gridded Object 2 (laygo2) is an open-source project that offers libraries for automating the creation of custom circuit layouts, which satisfy design rules, performance and area efficiency in advanced CMOS processes. laygo2 aims to 1) streamline the layout design process through automation, while 2) provide rich parameterization capability and 3) compability with cutting-edge technologies such as FinFET, making it easier for circuit/mask designers to enhance their design productivity.

laygo2 is implemented with a comprehensive collection of layout object classes and methods, written in the Python programmanging language, rending it suitible for code-based layout generation.

laygo2 is composed of the following subpackages, each serving a distinct purpose:

• laygo2.object: houses the core object classes, responsible for defining physical layout structures and design hierarchies.

• laygo2.interface: implements the interfaces to external data structures and EDA tools (yaml, skill, BAG, GDS, matplotlib and others).

• laygo2.util: provides a range of utility functions for internal use.
