Barnett co-founded Xilinx with
Ross Freeman and
Bernard Vonderschmitt in 1984. The three individuals had been working together at Zilog where Freeman wished to develop chips that were blank and users could program the logic themselves and envisioned the field-programmable gate array. Zilog executives were not interested in developing this technology, which prompted the three Zilog engineers to leave the company and pursue the concept independently. They raised $4.25 million in venture capital from Hambrecht & Quist and Kleiner Perkins Caufield and Byers, among others, to form
Xilinx, Inc., in 1984. ==Legacy==
