From Code to Chip

This book shows how the layout of an analog circuit can be automatically generated in a fully open-source way. Based on an exemplary design flow, it introduces and explains the necessary steps for transforming a SPICE netlist into a layout, which can be inspected by the open-source layout editor Magic VLSI. This is done by using the industry’s first open-source process design kit SKY130. Furthermore, the implementation of the design flow in the programming language Python is available as open-source on GitHub. In addition, this book: - Describes in detail data structures necessary for implementing an analog layout design automation tool. - Scopes and explains the entire design flow, starting from a netlist and ending in a layout. - Provides succinct introductions to key topics, with references as needed for further technical depth.
