Key Responsibilities

- Own and manage timing constraints (SDC) development and maintenance for complex SoC designs.
- Define and manage clocks, clock relationships, and timing exceptions using XML-based or equivalent constraint methodologies.
- Develop, review, and validate timing constraints with strong focus on quality and accuracy.
- Independently manage and enhance constraint build flows and automation methodologies.
- Perform debug and analysis related to GCA, TCM, minimum pulse width, and minimum period violations.
- Collaborate closely with Physical Design (PD) teams to address ad-hoc constraint development and timing closure requirements.
- Analyze design specifications and translate functional/timing requirements into robust timing constraints.
- Drive constraint signoff activities and ensure timing intent is accurately captured throughout the design cycle.

Required Skills

- Strong expertise in SDC creation, timing constraint development, and validation.
- Good understanding of clock architecture, generated clocks, clock groups, and timing relationships.
- Hands-on experience with constraint verification, timing analysis, and debug methodologies.
- Ability to independently build, maintain, and troubleshoot constraint flows.
- Experience in debugging GCA/TCM issues and handling min pulse width and min period checks.
- Strong analytical and problem-solving skills with the ability to work on challenging timing scenarios.
- Good understanding of digital design and static timing analysis (STA) concepts.

Preferred Qualifications

- Experience with SerDes-based protocols and high-speed interfaces.
- Ability to interpret protocol specifications and develop timing constraints based on documented requirements.
- Familiarity with advanced SoC design flows and industry-standard STA tools.

Experience

- Typically 5+ years of experience in Timing Constraints, STA, or Physical Design support roles within VLSI/ASIC development environments.
