In order to design the digital part of mixed-signal circuits, the project selected the Alliance OSEDA tool chain from Sorbonne Université-LIP6, and a new open source standard cell library which is based on Alliance included standard cell library. The project has successfully fabricated LSI chips with Alliance using the 180nm, 350nm ROHM technology and the 0.6um Phenitec Semiconductor Corp. technology that will be presented and discussed.
The several benefits that OSEDA and OSHW can offer will be argued and the several difficulties that need to be overcome towards this goal will be pointed out. While several OSEDA and OSHW exist and can be used to perform a low-cost design, it will require a larger collective effort to make OSEDA and OSHW trustful and useful in the context of practical and robust designs.
