A "Full Chip STA Lead" is a key role in semiconductor companies, responsible for leading Static Timing Analysis (STA) activities for complex full-chip designs. The job description for this role typically includes the following responsibilities and qualifications:

Responsibilities:

Timing Closure: Lead and manage the full-chip STA process to achieve timing closure goals, including setup and hold time analysis, clock domain crossing (CDC) analysis, and signal integrity (SI) analysis.
STA Methodology: Develop and implement STA methodologies and best practices to ensure accurate and efficient timing analysis of full-chip designs, including setup of timing constraints and constraints validation.
Tool Selection and Optimization: Evaluate, select, and optimize STA tools and scripts for timing analysis, including tools like Synopsys PrimeTime, Cadence Tempus, and Mentor Calibre.
Timing Constraints: Define, validate, and maintain timing constraints, including clock definitions, input/output delays, false path constraints, and multicycle paths.
Timing Analysis: Perform static timing analysis for full-chip designs, analyze timing paths, identify timing violations, and work with design teams to resolve timing issues.
Clock Domain Crossing (CDC) Analysis: Perform CDC analysis to identify and mitigate metastability issues, clock domain crossings, and data synchronization problems.
Signal Integrity (SI) Analysis: Collaborate with SI engineers to analyze signal integrity issues, including noise, jitter, and crosstalk, and ensure timing closure with SI constraints.
Collaboration: Work closely with design teams, physical design teams, verification teams, and other stakeholders to understand design requirements, resolve timing issues, and ensure successful tape-out.
Documentation: Maintain documentation related to timing constraints, STA reports, timing closure status, and issues encountered during STA activities.

Qualifications:

Education: Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, or a related field.
Experience: Several years of experience in static timing analysis (STA) for full-chip designs, including experience in a lead or senior role.
STA Tools: Proficiency in using industry-standard STA tools such as Synopsys PrimeTime, Cadence Tempus, and Mentor Calibre, including scripting skills in Tcl, Perl, or Python for automation.
Timing Closure: Expertise in achieving timing closure for full-chip designs, including understanding of setup and hold time violations, clock tree synthesis (CTS), and optimization techniques.
CDC and SI Analysis: Experience in clock domain crossing (CDC) analysis, signal integrity (SI) analysis, and related methodologies to ensure reliable and robust chip performance.
Collaboration Skills: Strong communication, teamwork, and collaboration skills to work effectively with cross-functional teams and stakeholders, including design, physical design, and verification teams.
Problem-Solving: Excellent analytical and problem-solving skills to identify and resolve timing issues, debug STA failures, and propose effective solutions.
Leadership: Leadership skills to lead and mentor junior STA engineers, drive timing closure activities, and manage project timelines and deliverables.

Overall, a Full Chip STA Lead plays a critical role in ensuring the timing integrity and reliability of full-chip designs, contributing to the successful tape-out and production of high-quality semiconductor products
