Senior Engineer

essolve STA Engineer (4+ Years Experience)

Location: Bangalore

Job Type: Full-Time

Experience: 48 years

Domain: ASIC / SoC Static Timing Analysis

Job Summary

Tessolve is seeking a skilled STA Engineer with 4+ years of hands-on experience in block-level and/or chip-level timing analysis and closure. The ideal candidate should be proficient with industry-standard timing tools, sign-off methodologies, and timing constraints development for advanced technology nodes.

Key Responsibilities

Static Timing Analysis & Closure

• Perform block-level and top-level STA using Synopsys PrimeTime or equivalent sign-off tools.
• Develop, validate, and maintain timing constraints (SDC) for functional and test modes.
• Analyze and resolve setup, hold, DRV, SI/Noise , and cross-corner timing issues .
• Drive timing closure by coordinating with RTL, physical design, DFT, and architecture teams.

Timing Sign-Off & Debug

• Perform multi-mode, multi-corner (MMMC) analysis for all PVT corners.
• Support ECO generation and validation for timing fixes (functional & timing ECOs).
• Debug clock tree, macro timing, and route-based timing problems.
• Run and interpret report timing, report_timing_summary, path-group analysis , etc.

Tool & Flow Expertise

• Work with Synopsys PrimeTime (PT/PTS), Cadence Tempus, or equivalent STA sign-off tools.
• Understand modeling of libraries (LIB), SDF, SPEF, OCV/AOCV/POCV , and latency models.
• Support methodology improvements for timing closure and sign-off automation.

Required Skills & Experience

• 4+ years of hands-on experience in STA for ASIC / SoC projects.
• Strong knowledge of:
• SDC creation and validation
• Setup/Hold analysis and fixes
• Noise/SI timing checks
• MMMC timing methodologies
• OCV, AOCV, POCV modeling
• SPEF/SDF/LIB interpretation
• Solid understanding of digital design fundamentals , clocking concepts, and physical design interactions.
• Hands-on experience with Synopsys PrimeTime (preferred) or Cadence Tempus.
• Proficiency with Tcl scripting for automation.
