OpenCores

OpenCores is a community developing digital open-source hardware through electronic design automation (EDA), with a similar ethos to the free software movement. OpenCores hopes to eliminate redundant design work and significantly reduce development costs. A number of companies have been reported as adopting OpenCores IP in chips,^[1][2] or as adjuncts to EDA tools.^[3][4] OpenCores is also sometimes cited as an example of open source in the electronics hardware community.^[5]

OpenCores has always been a commercially owned organization. In 2015, its core active users established the independent Free and Open Source Silicon Foundation (FOSSi Foundation), and created another directory on the librecores.org^[6] website as the basis for all future development, independent of commercial control. It has been shut down to redirect to a post on the FOSSi Foundation website seven years later in favor of a simple web search, reasoning that "free and open source silicon is no longer a dream".^[7]
