Company: Nsemi Design Services
As an STA (Static Timing Analysis) Engineer at Nsemi, you’ll play a crucial role in ensuring our digital designs meet timing requirements and performance standards. You will be responsible for performing timing analysis, identifying critical paths, and optimising designs for timing closure. Your expertise in STA tools and methodologies will be essential in delivering high-quality, reliable semiconductor solutions.
Qualification Required
- Typically requires a minimum of 3+ years of experience.
- Bachelor’s / Master’s Degree in E&E and E&C
- Strong communication & teamwork skills
Roles And Responsibilities
- Timing Constraint Generation: Work with design and architecture teams to define and generate timing constraints that specify the desired timing requirements for the design.
- STA Setup: Set up and configure STA tools (e.g., Cadence Encounter, Synopsys PrimeTime) for the analysis, including library characterisation, delay models, and clock definitions.
- Timing Analysis: Perform static timing analysis to evaluate setup and hold times, clock-to-q delays, and other timing metrics. Ensure that the design meets timing requirements for various corners and operating conditions (e.g., process, voltage, temperature variations).
- Clock Domain Crossing (CDC) Analysis: Identify and analyse asynchronous signals crossing between different clock domains to ensure proper synchronisation and to avoid metastability issues.
- Multicycle Paths (MCP) and False Paths: Define and analyse multicycle paths and false paths to accurately capture the designs timing constraints.
- Timing Closure: Collaborate with RTL and physical design teams to achieve timing closure by optimising the design or constraints. Perform incremental and formal ECO (Engineering Change Order) analysis to address timing issues.
- Clock Tree Synthesis (CTS): Work with CTS engineers to ensure that the clock tree meets timing requirements and minimises clock skew and jitter.
- Post-Layout STA: Perform post-layout STA to account for parasitic capacitance and resistance effects introduced during the physical design phase. Identify and resolve timing violations and sign-off on the final timing closure.
- Timing Margins: Analyse timing margins to account for variability and manufacturing process variations, ensuring robust operation.
- Report Generation: Prepare detailed timing analysis reports, including timing paths, violations, and suggestions for timing optimisation.
- Cross-Functional Collaboration: Collaborate closely with RTL designers, physical designers, DFT (Design for Test) engineers, and verification teams to resolve timing-related issues.
- Methodology Development: Contribute to the development and improvement of STA methodologies and flows to enhance efficiency and accuracy.
