With SiFive, the future of RISC-V has no limits.

As an Intern on the Core IP Physical Design team, you will participate in development of Digital IC (RISC-V) physical design analysis and flows. There will be an emphasis on analyzing physical designs at different stages in place and route implementation:

  • Testing flow changes to achieve desired results improvement.
  • Working with tools from multiple market leading EDA vendors and incorporate scripting changes specific to SiFive designs.
  • Analysis of the design at different phases in the implementation process.
  • Develop scripts for design analysis.

What You Will Learn:

  • Thorough knowledge of each step of the physical design flow and how to analyze the design in the different stages.
  • Hands-on experience with EDA design tools and how to tune them to get desired results.
  • The power of using TCL and potentially other languages for analysis and design flow manipulation.
  • How to collaborate with other team members on debugging and resolving design related issues.


  • Pursuing a Bachelor’s (Sr), Master's or PhD in Computer Engineering, Computer Science, Electrical Engineering, or a similar discipline. 
  • Some coding experience either in Python, TCL, C, or Perl.
  • Knowledge of digital IC circuits and design principles.
  • Some experience with a Linux/Unix compute environment.
