Ordie

The field of open silicon is still in its infancy, and while the story on digital logic generation is good, analogue is still a work in progress, and full system integration is only just beginning. The Ordie project will characterize available analogue and digital blocks, integrate them, and create simulation and test software to validate them both pre- and post-production. In this way, the Ordie project will create open, fully-verified silicon chips where every aspect of the part is inspectable down to the raw GDS files. These parts will be usable in some aspects of projects such as Betrusted, where they may be used to replace some of the proprietary silicon with open variants. Along the way it will develop a circuit that enumerates over USB, be able to address various debug structures using existing Wishbone USB and Spibone debugging, and develop a buck regulator, useful for powering on-die structures.The on-chip blocks will be documented using reference systems such as lxsocdoc.
