任职要求
• MS/BS in EE or equivalent experience • Minimum 5+ years of experience as a SI/PI engineer • Deep understanding of electromagnetics, specifically electromagnetic waves including transmission line theory and via properties • Proficient with HFSS, Sigrity, Hspice, and/or other simulation tools • Experienced with Cadence Allegro PCB designer and Constraints Manager • Understanding of high volume manufacturing variations and impact to channel signal integrity • Exposure to lab measurements including VNA & TDR experience • Passionate about SI/PI work • Good written & verbal interpersonal skills in English Ways to stand out from the crowd: • Familiarity with NRZ/PAM-4/Duo-binary signaling schemes • Exposure to interface timing budgets and system modeling • Familiarity with high-speed I/O design concepts including clock generation, transmitter & receiver design, and equalization schemes • PDN analyses including model generation and time domain simulation • Experience w/ Matlab, Python, and C as well as exposure to package design
工作职责
• Drive board/system level signal and power integrity requirements • Lead board/system SI/PI design activities, including PCB stackup/material selection, design guide implementation, layout review, and post-layout analysis • Work closely with Architecture, ASIC, Mixed Signal, Package, and PCB Design teams to design and ensure system SI/PI performance meets expectation before Gerber out, also work closely with Design Validation teams to support SI/PI failure analysis • Develop novel algorithms & new methodologies to improve SI/PI modeling efforts • Work with Application Engineering teams to support customers w/ SI/PI questions • VNA & TDR measurements to support model correlation efforts and improve confidence in design stage
• Analyze pre-production silicon in state of the art process technologies for performance, power, yield, and quality to define the world’s fastest power-shipping products. • Help design tools to automate product definitions, data collection, test case execution, and results analysis. • Develop post-silicon methodologies to characterize silicon features, correlate silicon behavior with simulations and provide design feedback. • Your expertise will help architect essential next-generation product features and work with multi-functional teams to drive them to production. • Find creative solutions to complex silicon and system level problems in order to enable product shipment. • We work alongside system architects, chip and board designers, software/firmware engineers, HW/SW applications engineering, process/reliability experts, ATE engineers, product managers, sales, and operations, in a dynamic, high-energy work environment to bring industry-defining products to market.
