Power, Performance, and Area (PPA)

targets. Key Responsibilities 1. Logic Synthesis & PPA Optimization Perform physical-aware RTL-to-gate synthesis for complex digital designs. Optimize synthesis results for

Power, Performance, and Area (PPA)

targets. Analyze synthesis reports and identify opportunities for timing, area, and power improvements. Work with RTL designers to resolve synthesis-related issues and improve RTL quality. Support synthesis flows across block-level and top-level designs. 2. Constraint Development & Management Develop, review, validate, and debug

SDC timing constraints for block-level and top-level designs. Define and maintain constraints for functional, scan, and DFT modes . Handle clock definitions, generated clocks, clock relationships, I/O constraints, false paths, multicycle paths, and case analysis. Debug constraint-related timing issues and ensure constraint completeness and correctness. 3. Static Timing Analysis & Sign-Off Perform

Static Timing Analysis (STA)

across

Multi-Corner Multi-Mode (MMMC)

scenarios. Drive timing sign-off for setup, hold, recovery, removal, and clock-gating checks .



Analyze critical paths, timing violations, clock interactions, and design bottlenecks. Understand and account for clock skew, jitter, latency, uncertainty, and variation effects . Perform timing analysis across functional and DFT/scan modes. Support and debug

CDC-related timing issues in collaboration with RTL/CDC teams. 4. Timing Closure & ECO Identify critical timing paths and develop effective strategies for timing closure. Generate, implement, and validate timing and functional ECOs . Analyze the impact of ECOs on timing, area, power, and functionality. Work closely with

Physical Design/P&R; teams to resolve post-placement and post-route timing issues. Support iterative synthesis, implementation, and timing optimization until sign-off. 5.

Formal Equivalence Checking

Perform formal equivalence checking between RTL and synthesized/optimized netlists. Validate functional correctness following synthesis optimizations and ECO changes. Debug equivalence failures and collaborate with RTL and design teams to resolve issues. Ensure design changes maintain functional equivalence across implementation stages.
