Responsibilities

- Signal Integrity (SI)
- Perform SI analysis for high‑speed interfaces such as DDR, PCIe, Ethernet, SERDES, LVDS, USB, HDMI, and similar protocols
- Analyze and optimize signal quality parameters including jitter, eye diagram, crosstalk, reflections, and skew
- Define routing constraints, impedance control, termination schemes, and stack‑up recommendations
- Review PCB layouts and provide SI‑driven design feedback to layout teams

- Power Integrity (PI)
- Design and analyze Power Delivery Networks (PDN) for low noise and reliable voltage delivery
- Perform decoupling capacitor selection, placement, and optimization
- Analyze power plane impedance, IR drop, and transient response
- Support switching regulator and point‑of‑load (POL) power architecture considerations

- Simulation & Analysis
- Run pre‑layout and post‑layout SI/PI simulations
- Perform What‑if analysis to assess design trade‑offs
- Correlate simulation results with lab measurements

- Validation & Debug
- Support lab validation using high‑speed measurement tools




- Analyze and debug SI/PI issues during board bring‑up
- Drive root cause analysis for signal and power related failures

- Documentation & Collaboration
- Create SI/PI guidelines, design checklists, and reports
