Sr. EMIR Engineer, Annapurna Labs - Cloud Scale Machine Learning
About The Position
Our Machine Learning Acceleration (MLA) team develops the Inferentia and Trainium SoCs that are used to power today’s AI workloads in datacenters all around the world. As a Sr. EMIR Engineer, you’ll contribute to the EMIR sign-off of our SoCs and help maintain a high bar on quality. We’re searching for an experienced EMIR engineer with a proven track record of handling challenges at scale. In this role, you’ll be working directly with architects, designers, verification engineers, power integrity engineers and physical design experts - defining best practices in power grid design, developing test cases & vectors to model demand currents accurately, modeling & signing-off EMIR taking into account board and package impact, advancing the state-of-the-art in EMIR analysis and modeling.
Requirements
- 5+ years of ASIC implementation, synthesis, STA and physical design in deep sub-micron nodes (16nm or smaller) experience
- BS + 6yrs or MS + 5yrs or PhD + 3yr in EE/CS
- Expert on EMIR analysis tools like Redhawk-SC or Voltus or similar
- Deep, circuit-level understanding of power, EM and IR
- Ability to give feedback to RTL designers and Physical Designers on how to reduce IR
- Highly proficient with scripting language (Tcl, Perl, Python or similar)
- Good understanding of Physical Design, EM/IR, Power Integrity, and Thermal at the die, package, board, and server level
Nice To Haves
- Familiarity with Make or similar for automation of EMIR rollups
- Experience with RTL design (System verilog)
- Experience with PnR tools (FusionCompiler or Innovus)
- Familiarity with Power analysis tools (PrimePower or similar)
- Familiarity with timing analysis tools (PrimeTime or similar)
- Some experience with lab equipment and capable of doing lab power analysis
Responsibilities
- Design & analyze power grids
- Setup flows for EMIR analysis
- Run EMIR analysis for large subsystems, SoCs
- Partner with EDA tool vendors to develop / evaluate new methodologies for EMIR analysis
- Develop and maintain dashboards for EMIR rollups
- Work with designers, architects, Verification engineers and Physical Design engineers to develop vectors for IR analysis, Thermal analysis and power estimation
- Design and evaluate power grids
- Working with designers, architects and verification engineers to come up with worst-case vectors for power and IR analysis
- Root cause causes of low annotation or low switching coverage with vectors
- Develop & maintain dashboards to track EMIR status
- Root cause causes of IR drop and suggest solutions to fix
- Combine IR analysis of SoC with IR at board and package level (concurrent IR analysis)
- Do post-silicon power measurements and correlate with simulation.
- Innovate on ways to model VR, board and package impact on voltage drop more accurately.
- Partner with EDA tool vendors to develop / evaluate new methodologies for EMIR analysis
