About

Currently working at Nvidia as a Senior Physical Design Engineer. I have worked on various aspects of the ASIC design flow ranging from design synthesis to place and route, timing convergence, power optimization and full-chip STA analysis/closure of advanced node designs. My prior industry experience also includes the design of reference platform designs for client SoC validation.

Promoted

Dec 2017Jul 2021 · 3 yrs 7 mos · Greater Bengaluru Area

  • Areas of Proficiency:
  • 3+ years of experience in Physical Design Implementation (Synthesis, floorplanning, CTS, Routing) with STA convergence and Reliability Verification of complex networking IP blocks based on Intel’s 10nm and TSMC’s 7nm process nodes. Familiar with backend layout, LEC sign-off flows and the Synopsys EDA tool stack.
  • Shared Slice Controller IP:
  • Responsible for design synthesis, placement, convergence and sign-off of a complicated controller block with multiple macros and high criss-cross routing density.
  • Engaged with RTL owners to get a deep understanding of the block’s architecture to achieve an optimal floorplan and accelerate convergence. Converged the design to tape-in within stringent timelines.
  • Worked with floorplan owners to mitigate challenges arising due to multi-instantiated blocks in the IP floorplan.
  • Handled subsystem timing analysis and generated ECOs for interface and partition level STA sign-off.
  • Scalable HPC Coherent Mesh Network IP:
  • Design owner for Synthesis and PnR execution of multiple high-speed design blocks in a mesh network.
  • Finalized custom place-and-route recipes to optimize critical data paths and reduce clock skew to achieve timing convergence and improve overall design QoR.
  • Reliability Verification owner for all partitions in an SoC IP. Performed Power Grid weakness checks, SignalEM and Dynamic/Static IR drop analysis with Redhawk for all partitions in an SoC IP.
  • Intel 10nm wireless base station SoC:
  • Responsible for PnR execution of multiple blocks including complex designs from the Remote Direct Memory Access (RDMA) sub-IP.
  • Automated generation of multiple ECO’s to fix timing, MaxTrans and MaxCap violations for signoff convergence.
  • Fixed critical Pattern must-join requirements through tool-based automation and DRC aware tail end fixes. Worked on Full-chip layout integration, fixed physical DRC and density violations for sub-IPs.
