Corporate history
Open-Silicon was founded in 2003 by Naveed Sherwani, Satya Gupta and Scott Houghton. Initial funding was provided by Sequoia Capital, Norwest Venture Partners, and InterWest Partners.[2] In December 2007 Unicorn Investment Bank acquired 75% of Open-Silicon for $190M, with the rest of the company employee-owned.[3]
In May 2007, Open-Silicon acquired Zenasis Technologies, a maker of processor optimization EDA software.[4] This technology has also been expanded by Open-Silicon to focus on low power design and process variability management.[5]
In 2009 Open-Silicon acquired design services firm Silicon Logic Engineering (SLE). This acquisition has enhanced the company's derivative IC design capabilities.[6] In 2010 the company opened new facilities in Research Triangle Park, North Carolina, and Pune, India, to provide additional support for derivative IC design.
Open-Silicon's business model for its ASIC development process was called the OpenMODEL.[7][1] In 2012, Open-Silicon acquired and grew substantial design operations in Pakistan and Taiwan.
On August 17, 2020, SiFive acquired Open-Silicon and renamed it OpenFive, an independent business unit of SiFive. On Sept. 1, 2022, Canadian semiconductor licensing company Alphawave Semi acquired SiFive’s OpenFive business unit for $210 million.
