Intern - Microprocessor Verification

SiFive is the leading provider of market-ready processor core IP, development tools and silicon solutions based on the free and open RISC-V instruction set architecture. Led by a team of seasoned silicon executives and the RISC-V inventors, SiFive helps SoC designers reduce time-to-market and realize cost savings with customized, open-architecture processor cores, and democratizes access to optimized silicon by enabling system designers in all market verticals to build customized RISC-V based semiconductors.
At SiFive, you’ll be part of a fun, engaging team and be afforded the opportunity to grow within the company. You will work side-by-side with the founders of RISC-V and bring to fruition the new RISC-V architecture and enable its rapid adoption by implementing new tools, breakthrough design methods and services. We need people who are trail-blazers, aren’t afraid to take a chance, and don’t always “go with the flow”.
The verification engineer will work with the creators of RISC-V to create tests for the latest RISC-V processor and its subsystems. The engineer will have the opportunity to learn about the latest SiFive CPU offerings and its features, to create testplans which will exercise all functionality of the design, and to create portable tests using C and/or assembly. He/she will also be responsible for debugging failing tests through the instruction trace log and waveform to root cause failure.
