RISC-V
Full-Time

Physical Design / GateSim Validation Engineer

RISC-V is a groundbreaking CPU instruction set and architecture. Along with being an open-source instruction set, RISC-V is informed by decades of industry experience with various RISC processor designs, while being unencumbered with the necessity of backward compatibility. It is a unique opportunity to base a processor design on sound engineering principles, and the successful applicant will have comprehensive daily hands-on exposure to this architecture. While several companies are pursuing RISC-V design, only SiFive is founded and actively managed by the inventors of RISC-V. This is not an academic exercise; we have real customers and real silicon. 
You will develop methodology to run gatesim (GLS) on automated generated design in order to estimate accurate average/max power consumption, timing, modeling issues.

The Challenge

  • Developing efficient gatesim methodology to support auto-generated customized designs;
  • Applying to zero delay gatesims;
  • Providing high confidence tapeout for SoC products;
  • Developing process to interact with design, verification, and implement teams with gatesim.

What you bring to the challenge

  • Good waveform debugging skills:
  • Understanding timing issues;
  • Debugging through various IPs in gate level netlist;
  • Knowledge of X-prop issue;
  • Knowledge of Standard Delay Format (SDF);
  • Verilog modeling:
  • Good understanding of blocking / non-blocking assignments;
  • Good understanding of UDPs;
  • Knowledge of Simulation glitches / races;
  • Knowledge of Event queue.
