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.[1] In December 2007 Unicorn Investment Bank acquired 75% of Open-Silicon for $190M, with the rest of the company employee-owned.[2]

In May 2007, Open-Silicon acquired Zenasis Technologies, a maker of processor optimization EDA software.[3] This technology has also been expanded by Open-Silicon to focus on low power design and process variability management.[4]

In 2009 Open-Silicon acquired design services firm Silicon Logic Engineering (SLE). This acquisition has enhanced the company's derivative IC design capabilities.[5] In 2010 the company opened new facilities in Research Triangle Park, North Carolina, and Pune, India, to provide additional support for derivative IC design.

In 2012, Open-Silicon acquired and grew substantial design operations in Pakistan and Taiwan.

On August 17, 2020, SiFive acquires Open-Silicon and names it OpenFive, an independent business unit of SiFive.

On Sept. 1, 2022, Canadian semiconductor licensing company Alphawave acquires SiFive’s OpenFive business unit for $210 million.
