Job summary

SiFive, a leader in RISC-V, seeks a Senior Formal Verification Engineer in Bengaluru to drive formal verification for complex digital designs, including RISC-V cores and IP blocks. You will build verification environments using Chisel/Scala, write formal properties, and collaborate with design teams to improve correctness and coverage.

The ideal candidate has 7+ years in digital hardware verification, deep knowledge of formal methods, TCL scripting, and experience with chisel-formal tools.

Qualifications

• Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, or a related field.
• 7+ years of hands-on experience in formal verification of digital hardware designs.
• Proficiency in Scala programming, with hands-on experience in Chisel.
• Strong understanding of formal verification methodologies (e.g., assertion-based verification, model checking, equivalence checking).

Responsibilities

• Develop and implement formal verification plans for complex digital designs, primarily targeting RISC-V processors and other IP blocks designed in Chisel.
• Write and debug formal properties (assertions and assumptions) in Chisel/Scala to specify design behavior and identify corner-case bugs.
• Utilize formal verification tools to prove design correctness and uncover potential issues.
• Collaborate closely with design engineers to understand design specifications, review architectures, and provide formal verification feedback.
• Develop verification environments and infrastructure using Chisel, Scala, and TCL scripting.
• Identify and implement strategies for improving formal verification efficiency and coverage, including functional coverage and constrained-random verification techniques seen in methodologies like UVM adapted for Chisel.
• Analyze formal verification results, debug failures, and work with the design team to resolve issues.
• Contribute to the continuous improvement of our formal verification flows and methodologies.
