Experience : 5+years Location : Bangalore Job Description: As an STA Engineer, you will be responsible for timing closure and verification of complex ASIC or SoC designs. You will work closely with cross-functional teams including physical design, logic design, and architecture to ensure timing requirements are met across various design stages and process corners. Key Responsibilities: Own full-chip and block-level timing closure across RTL, synthesis, and physical implementation stages. Develop and validate timing constraints (SDC) for blocks, partitions, and full-chip designs. Perform timing analysis using industry-standard tools (e.g., PrimeTime, Tempus). Collaborate with design and architecture teams to define timing requirements and resolve timing violations. Analyze timing scenarios, margins, and corner cases. Integrate third-party IPs and derive timing signoff requirements. Optimize timing paths and reduce signoff corners by merging modes. Automate STA flows using scripting languages. Support test mode timing closure (e.g., scan shift, scan capture, BIST). Primary Skills: Static Timing Analysis (STA): Deep expertise in STA tools like Synopsys PrimeTime, Cadence Tempus. Timing Constraints Development: Proficient in writing and validating SDC constraints. Scripting Languages: Strong skills in TCL, Perl, Python for automation. ASIC/SoC Design Knowledge: Understanding of synthesis, physical design, and backend flows. Corner and Mode Analysis: Experience with timing corners, process variations, and signal integrity. Constraint Debugging: Familiarity with tools like Synopsys GCA (Galaxy Constraint Analyzer). Secondary Skills: Tool Proficiency: Experience with tools like Genus, Timevision, Fishtail, Tweaker. Low-Power Design: Knowledge of UPF, multi-voltage domains, and power gating. Custom IP Integration: Handling of PLLs, SerDes, ADC/DAC, GPIO, HSIO. Communication & Collaboration: Strong interpersonal skills for cross-functional teamwork. Mentorship: Ability to guide and mentor junior engineers. Process Node Experience: Familiarity with advanced nodes (3nm, 5nm, 7nm, FinFET). Show more Show less
