System and Chip Simulation

SYSTEM ARCHITECT - MODELING

We are looking for an infrastructure-savvy System Architect who comprehensively understands both large-scale distributed systems and networking silicon design, and is able to specify, model, and simulate silicon chip and system level behavior to advance the definition of a breakthrough category-defining infrastructure networking product. 

Scope 

• Ownership for chip/system level architecture models at the performance and functional level (device/block C/C++ models, ns3 models). Own device architecture validation, device-level optimizations, feasibility proof, functional interaction and correctness with system software and networking stacks.

• Ownership for equivalence methodology to RTL with a view into architecture/design co-verification.

• Ownership of device and system fitness for large-scale distributed applications such as deep learning.

• Ownership of key areas of chip-level architecture definition and implementation details, working from high-level concepts/problems/specifications and customer inputs.

 Responsibilities 

• Develop and maintain the simulation methodology for performance modeling for the device architecture including queueing & packet processing models. Incorporate functional models into performance models.

• Own coding of the models in C/C++ and roadmap/strategy/interlocks for model development. Produce detailed documentation for the models, including pseudo-code and equivalence checking to RTL. 

• Fully specify the methodology and software required to exercise the models; log results, perform regression testing, or correlate against functional and RTL DV simulations.

• Drive product architecture definition, tradeoffs, and validation in new areas/directions, including network / system / I/O virtualization, security, root of trust, system/board management.

• Leverage simulation efforts for customer validation by adjusting the model to per-customer variants, drive evolution of the models to achieve both customer and internal development goals.

• Create specifications for software and for microarchitecture teams, and collaborate closely with both teams towards meeting aggressive product specifications and schedules.

• Drive innovations at the system and chip level to address technical challenges in front of the company.

Qualifications

• Significant experience in processor or networking chip architecture definition, modeling and/or validation at an industry or product category leader.

• Must have coded and validated silicon/system behavioral models in C, systemC, or C++; experience with ns3 or other multi-node network simulators a plus.

• Hands-on knowledge and/or programming experience with distributed cluster-scale applications.

• Track record of successful involvement in infrastructure product execution/deployment.

• Solid programming skills in C/C++; fluency in scripting languages (Python, Perl) desired.

• Understanding of silicon chip architecture and fundamentals required; proficiency in Verilog/SystemVerilog and testbench creation a plus.
