Job Description:

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.​

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 hardware description language.
• Strong understanding of formal verification methodologies (e.g., assertion-based verification, model checking, equivalence checking).
• Experience in writing effective formal properties and assertions. Tools like chisel-formal use Formal traits and assert statements within Chisel modules for this purpose github.com.
• Familiarity with formal verification tools and their application
• Experience with TCL scripting for tool automation and flow development.
• Solid understanding of digital design principles, computer architecture, and FPGA/ASIC design flows.
• Excellent problem-solving skills and a keen eye for detail.
• Strong communication and collaboration abilities.
