About the role
- You will work closely with package, PCB, ASIC, and system engineers to analyze high-speed interfaces, extract channel models, and improve signal quality across our accelerator platforms.
Responsibilities
- Perform channel analysis for high-speed interfaces including PCIe, Ethernet, and other SerDes links.
- Extract and validate S-parameter models from package and PCB layouts.
- Generate channel compliance reports and support design reviews.
- Build and validate 3D electromagnetic models using Ansys HFSS. Develop board and package channel models from ECAD design databases. Correlate simulation results with measurements and lab data. Support mixed package-board channel simulations and optimization.
- Partner with PCB layout, package, hardware, and ASIC teams to improve signal integrity. Identify root causes of channel degradation and propose design improvements. Contribute to SI design guidelines and best practices.
- Extracting S-parameter models from package and board designs for PCIe channels.
- Building HFSS models of high-speed breakout regions and BGA transitions.
- Developing automated workflows for SI simulation and report generation.
- Coursework or project experience in signal integrity, electromagnetics, RF, microwave engineering, or high-speed digital design.
Requirements
- Familiarity with transmission line theory and S-parameters.
