• Strong debugging, analytical, problem-solving, communication, and stakeholder management skills.
• Ability to work effectively with cross-functional global engineering teams in fast-paced semiconductor development programs.

Responsibilities

• Execute Gate-Level Simulations (GLS) for IP, subsystem, and SoC-level designs using netlists generated from synthesis and implementation flows.
• Perform SDF annotation and timing-aware simulations to validate setup, hold, recovery, and removal timing requirements.
• Analyze and debug timing violations, race conditions, metastability issues, and X-propagation behaviors.
• Validate reset sequences, clock-domain crossings (CDC), reset-domain crossings (RDC), and power-up initialization scenarios.
• Support Low-Power GLS Verification involving UPF/CPF, power gating, retention, isolation, and state restoration checks.
• Collaborate with RTL, Physical Design, STA, DFT, and Design Verification teams to identify and resolve implementation-related issues.
• Perform post-synthesis and post-layout functional verification to ensure design equivalence and correctness.
• Analyze simulation logs, waveform dumps, and timing reports to root-cause GLS failures.
• Develop and enhance automation frameworks for GLS execution, regression management, and report generation.
• Create verification plans, coverage reports, debug documentation, and signoff reports.
• Participate in design reviews, customer discussions, and methodology improvements to enhance GLS quality and efficiency.
