The Cisco Enterprise Access Switching SI team is seeking a Signal Integrity Engineer for design and analysis of high-speed components, interfaces and power distribution network. As a member the of Enterprise Access Switching SI team, you will help develop the Next Generations of Cisco Switch products, be a part of the definition and design of current and next generation ASIC, package, printed circuit board (PCB), and system interconnect. You will be working in a larger team working closely with system architects, logic designers, ASIC engineers, package engineers and versatile and knowledgeable SI/PI engineers in creation of next generation networking products.
What You'll Do:
- High-Speed link modeling and simulation, including high-speed I/O, IC package and system interconnections.
- Modeling and analyzing power delivery networks
- Electromagnetic modeling of complex 3-dimensional structures
- Perform pre- and post-route signal integrity analysis of both PCB and ASIC package designs
- Write signal integrity design guideline, test plan and test report
- Decide appropriate PCB material, stack-up, and work with vendors to address any DFM issues
- Support prototype function bring-up, validation and trouble-shooting
- Address signal integrity challenges on system high-speed interconnections, clock, power etc.
- Work closely with other hardware function teams including HW design, eCAD, Mechanical, Power, EMC, Diag to deliver first-class products.
Who You Are:
- PhD/MSEE or BSEE combined with 2+ years related experience
- Strong lab skills and measurement experience are desired (VNA, TDR, Real Time Scope, BERT)
- Strong tools knowledge (HFSS, ADS, Matlab, Cadence PowerSI/DC, Allegro, Simbeor, HSpice)
- Proficiency with 3-D field solvers and PI simulation tool such as PowerSI/DC
- Working experience with high speed NRZ and PAM4 SerDes, high-speed PCB/package development, and PI analysis is a plus
- Self-motivation, collaboration, strong communication and a desire to innovate are important
