LibrePDK

The LibrePDK is the library driving Danube River and the Pad Cell Generator

It is responsible for generating discrete parts with specific parameters for a specific process.

The properties of the parts can be optimized by utilizing the calibration values extracted from the measurements of taped out Danube River test wafers.

Adding a new technology

Technologies currently supported can be found in the technologies subfolder.

https://gitlab.libresilicon.com/generator-tools/librepdk/-/tree/master/LibrePDK/technologies?ref_type=heads

New technologies can be added by modifying scripts/update_technologies.sh and adding a tech.python script to the technologies folder.

After that, LibrePDK should be capable of auto discovering the new process after running the update script.

Installation

Installation of the library is as easy as running

pip install https+git://gitlab.libresilicon.com/generator-tools/librepdk.git

Components

LibrePDK provides generators for the basic components usually found within a VLSI/ULSI design, such as resistors, capacitors and transistors.

Capacitors

For now there's only simple small value caps available. Fingered and cup capacitors are still work in progress.

Resistors

There's two types of resistor structures available: Meander and strip resistors

Transistors

For now there's only single gate transistors (fingered transistors are still WIP)
