Range of USB IP solutions now available through DesignShare program designed to speed adoption of open source-based semiconductors

SAN MATEO, Calif., March 8, 2018 /PRNewswire/ -- SiFive, the leading provider of commercial RISC-V processor IP, today announced the addition of Corigine, a fabless semiconductor and IP company, to the DesignShare economy.

Through this partnership, Corigine will make available its USB-IF certified USB 3.1 Gen 1 and Gen 2, and USB 2.0 device, PC host and dual-role controller IP solutions for SiFive's Freedom platform as part of the DesignShare initiative.

Adoption of USB 3.1 Gen 2 is being driven by a broad range of applications, most many involving large file sizes or high-resolution video streams, that demand high bandwidth. System designers will benefit from Corigine's optimized, next-generation USB architecture that delivers the smallest size, lowest power and maximum configuration. The reduced gate count will contribute to less memory requirement, which lowers overall system cost. The logic sharing between device and host will further reduce the area consumption, providing the most economical and efficient solution for customers.

"The cost to bring a chip from design to realization continues to increase. This severely limits innovation to a handful of companies and inventors that have the money and time to come up with new designs," said Shafy Eltoukhy, VP of operations and head of DesignShare at SiFive. "Companies like Corigine recognize the opportunities DesignShare provides, and we're excited to bring new alternatives for aspiring inventors."

The DesignShare ecosystem provides any company, inventor or maker the ability to harness the power of custom silicon with little to no upfront risk. Companies like SiFive, Corigine and other DesignShare partners have developed efficient, pre-integrated solutions to enable users to develop their prototypes without the significant investment in upfront engineering costs typically required to bring a custom chip design to realization.

"The innovative approach of DesignShare is encouraging more silicon designs in an area where we see tremendous growth," said Ali Khan, VP of business and product development, Corigine. "Corigine is committed to providing differentiating IP solutions to benefit more customers, and we believe that participating in DesignShare will help lower the design barriers and add value to the semiconductor ecosystem."

Since DesignShare launched last year, the ecosystem has grown to include a wide range of IP solutions, from debug and trace technology to reconfigurable FPGA. For more information on DesignShare, visit
