essolve – STA Engineer (4+ Years Experience)
Location : Bangalore
Job Type : Full-Time
Experience : 4–8 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
