Static Timing Analysis (STA) Engineer
Job Summary
The Static Timing Analysis (STA) Engineer will own the timing sign-off and closure for complex integrated circuits (ICs) and/or System-on-Chips (SoCs).
This role involves defining and validating timing constraints, performing multi-mode multi-corner (MMMC) timing analysis, and collaborating with design and physical design teams to achieve the target operating frequency and performance metrics.
Key Responsibilities
- Timing Sign-off and Analysis
- Timing Closure Ownership: Drive all aspects of timing closure from pre-layout to post-layout for blocks, sub-systems, and/or the full chip.
- Constraint Management: Develop, validate, and maintain Synopsys Design Constraints (SDC) and timing constraints for all functional and test modes (e.g., Scan, MBIST).
- MMMC Analysis: Perform comprehensive timing analysis across multiple operating corners (Process, Voltage, Temperature - PVT) and various modes (Multi-Mode Multi-Corner).
- Critical Path Identification: Analyze timing reports to identify and debug critical paths and resolve all Setup and Hold violations.
- Signal Integrity (SI) & Noise: Incorporate advanced timing effects such as on-chip variation (OCV), signal integrity (crosstalk), and voltage drop (IR-drop aware STA) into the sign-off process.
Methodology and Flow
- Develop, maintain, and enhance STA flows and methodologies to improve efficiency, robustness, and reduce analysis runtime.
- Automate repetitive tasks and report generation using scripting languages.
- Generate final timing reports and sign-off collateral for tape-out.
Education
- Bachelor's or Master's degree in Electrical Engineering (EE), Electronics Engineering, VLSI, or a related field.
Technical Skills & Experience
- Experience: 3+ years of experience in STA.
- EDA Tools: Expert proficiency with industry-standard Electronic Design Automation (EDA) tools from vendors like Synopsys (e.g., Fusion Compiler, ICC2, Primetime), Cadence (e.g., Innovus), or Mentor Graphics.
Soft Skills
- Excellent analytical, debugging, and problem-solving skills.
- Strong verbal and written communication skills.
Ability to work effectively in a team environment and collaborate across different engineering disciplines.
