• Extensive experience in signal integrity analysis for high-speed serial interfaces (Ethernet, PCIe, DDR5).
• Proficiency in using EDA tools like Ansys SIWAVE, HFSS.
• Hands-on experience with time-domain and frequency-domain analysis, jitter, and eye-diagram analysis.
• Background in HSPICE simulations and model development.

Responsibilities

• Conduct signal integrity analysis and simulations for high-speed interfaces such as 112Gbps Ethernet, PCIe Gen5, and DDR5 interfaces.
• Develop and implement signal integrity guidelines for PCB design, ensuring high-performance and low-loss signal paths.
• Analyze and resolve signal integrity issues related to high-speed interfaces, including reflection, crosstalk, and PDN issues.
• Collaborate with PCB layout engineers to optimize design for signal integrity, ensuring compliance with electrical standards and high-speed design best practices.
• Perform time-domain and frequency-domain analysis, including loss, jitter, and eye-diagram analysis.
• Utilize EDA tools such as Ansys SIWAVE, HFSS, or similar for simulation and validation of signal integrity designs.
• Work closely with cross-functional teams to integrate signal integrity considerations into the overall hardware design process.
• Develop behavioural models based on measured signal integrity data to inform future design and simulation work.
• Conduct pre- and post-layout simulations and measurements for high-speed signal interfaces.
