- Expertise in clock domain crossing (CDC) in massive, multi-synchronous fabric environments and working knowledge of Python, Perl, or Tcl for developing design automation scripts and productivity tools.
- Knowledge of on-chip interconnect protocols such as AMBA 5 CHI, AXI5, and ACE.
- Deep understanding of cache coherency protocols (MESI/MOESI) and their hardware implementation within a fabric.
- Ability to work in the trenches with Verification teams to define coverage plans and debug complex testbench failures.
About the job
Be part of a team that pushes boundaries, developing custom silicon solutions that power the future of Google's direct-to-consumer products. You'll contribute to the innovation behind products loved by millions worldwide. Your expertise will shape the next generation of hardware experiences, delivering unparalleled performance, efficiency, and integration.
In this role, you will join a team developing Application-Specific Integrated Circuits (ASICs) to accelerate machine learning computation in data centers. You will collaborate with Architecture, Verification, Power and Performance, and Physical Design teams to specify and deliver quality designs for next-generation accelerators. You will solve technical problems through micro-architecture innovation and evaluate design trade-offs between performance and power.
Google's mission is to organize the world's information and make it universally accessible and useful. Our team combines the best of Google AI, Software, and Hardware to create radically helpful experiences. We research, design, and develop new technologies and hardware to make computing faster, seamless, and more powerful. We aim to make people's lives better through technology.
Responsibilities
- Own and execute the Register-Transfer Level (RTL) design and micro-architecture for high-performance fabrics and Network on Chip (NoC) subsystems from concept to tape-out. Run and analyze Power Performance Area (PPA) for the designs, and do design trade-offs to understand/optimize the design.
- Perform in-depth search performance analysis of NoC topologies, including latency modeling, bandwidth bottleneck identification, and arbitration tuning. Write production-quality SystemVerilog code for complex logic including credit-based flow control, asynchronous bridges, and cache coherency controllers.
- Drive front-end implementation tasks, run and debug Lint, CDC, RDC, and logical Equivalency Checks (LEC).
- Collaborate closely with physical design engineers to manually optimize floorplanning and timing closure for the fabric, ensuring high-frequency goals are met.
- Debug complex silicon issues and architectural bugs by digging into waveforms and gate-level simulations.
