Key Responsibilities

• Verification Strategy and Planning
• Develop and implement detailed, reusable test plans and verification strategies based on design requirements, architecture specifications, and product functional objectives.
• Environment Development
• Create and maintain robust, scalable verification environments using SystemVerilog and the Universal Verification Methodology (UVM).
• Test Development and Execution
• Write, execute, and manage targeted and constrained-random tests to verify functionality at various abstraction levels (unit, block, and full system).
• Verification IP and Modeling
• Develop reusable Verification IP (vIP) and Bus Functional Models (BFMs) to accurately simulate and verify interfaces (e.g., AMBA/AXI, I²C, SPI).
• Model-Based Verification
• Implement verification testbenches and comparison points derived from MathWorks Simulink models to ensure algorithms implemented in RTL match golden reference models.
• Coverage and Debugging
• Analyze test results, identify coverage gaps, and perform root-cause debugging of design issues in collaboration with the RTL design team.
• Utilize platforms such as Cadence vManager for regression management and coverage closure.
• Automation and Infrastructure
• Develop scripts (e.g., Python) for results processing, automated regression control, and streamlined CI/CD flows.
• Documentation and Review
• Provide timely progress reports, escalate critical issues when necessary, and actively participate in formal design and verification reviews.

Qualifications and Experience

• Required Background
  • Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or a related field.
  • Strong problem-solving, analytical, and communication skills (both written and verbal).
  • GPA of 3.0 or higher.
  • Proficiency in at least one scripting language (e.g., Python, Perl) for automation and data processing.
  • Extensive experience working in a UNIX/Linux development environment.
• Technical Expertise (Must Have)
  • Expertise in hardware verification languages: SystemVerilog and UVM.
  • Experience with advanced verification tools, particularly Cadence vManager (or similar regression management frameworks).
  • Strong foundation in C/C++ for model creation and co-simulation.
  • Experience with SoC verification.
  • Understanding of DSP verification methodologies.
• Highly Desired Skills and Domain Knowledge
  • Familiarity with Model-Based Design tools such as MathWorks Simulink for developing test vectors and reference models.
  • Working knowledge of embedded SoC fabric and ARM architecture (e.g., Cortex-A series).
  • Experience with hardware/software co-verification techniques and validating register maps accessed by firmware.
  • Practical experience with the overall FPGA/ASIC development and implementation flow.
  • Familiarity with high-speed protocols and the challenges of verifying designs used for RF/mixed-signal applications.
