Job Title: Formal Verification Architect, PCIe & UALink Controllers

Role Summary

We are looking for an experienced Formal Verification Architect to lead the formal verification strategy for high-performance PCIe and UALink controller IP.

The ideal candidate will combine deep formal verification expertise with strong protocol and microarchitecture knowledge. This is a hands-on technical leadership role responsible for defining verification architecture, identifying high-value formal targets, solving complex proof problems, and driving formal methods throughout the IP development lifecycle.

Key Responsibilities

  • Define the formal verification architecture and methodology for PCIe and UALink controller IP.
  • Develop block, subsystem, and end-to-end formal verification strategies spanning:
    • Protocol engines and state machines
    • Transaction and packet processing
    • Flow control and credit management
    • Ordering and dependency rules
    • Replay, retry, recovery, and error handling
    • Arbitration, scheduling, and resource management
    • Power/reset and initialization sequences
    • Configuration and control logic
  • Identify areas where formal verification can provide stronger coverage than simulation, especially for corner cases, deadlocks, livelocks, starvation, ordering violations, data integrity, and protocol compliance.
  • Architect assume-guarantee, compositional, abstraction, and formal decomposition strategies for large and complex controller designs.
  • Develop reusable SystemVerilog Assertions (SVA), properties, checkers, constraints, and formal verification IP.
  • Drive convergence of difficult proofs through abstraction, cut-points, state-space reduction, invariants, partitioning, and proof-debug techniques.
  • Work closely with RTL architects and designers to improve design-for-formal-verification and resolve architectural ambiguities early.
  • Define formal coverage criteria and establish metrics for proof completeness, unreachable states, vacuity, assumptions, and coverage closure.
  • Lead formal analysis of complex bug classes that are difficult to expose through constrained-random simulation.
  • Establish the appropriate balance between formal, simulation, emulation, and system-level verification.
  • Review verification plans and architecture specifications to identify formal opportunities and verification gaps.
  • Mentor verification engineers and raise formal verification capability across the broader controller verification organization.

Required Qualifications

  • BS/MS/PhD in Electrical Engineering, Computer Engineering, Computer Science, or related field.
  • Typically 15+ years of Verification experience, with significant hands-on formal verification experience of 5 years at least.
  • Deep expertise in property-based formal verification of complex RTL.
  • Deep knowledge of PCI Express, preferably PCIe 5.0/6.0/7.0 controller architecture and verification.
  • Experience with UALink, CXL, UCIe, Ethernet, or comparable high-performance interconnect protocols
  • Strong knowledge of:
    • SystemVerilog and SVA
    • Formal property development
    • Assumption and constraint modeling
    • Abstraction and decomposition
    • Formal coverage and proof closure
    • Counterexample analysis and debug
  • Hands-on experience with industry formal platforms such as Cadence Jasper or Equivalent
  • Experience applying formal verification to high-speed interconnect or networking controller designs.
