SiMa.ai, Inc.; Bengaluru; On-site; INR 7,000,000 - 12,000,000; Full time

Job summary

SiMa.ai, Inc. in Bangalore is seeking a Principal Engineer, Physical Design with 15+ years of experience in high-complexity SoC designs, including 7nm or lower nodes, to own floorplanning, P&R and integration.

The role requires on-site presence, strong PV/DRC knowledge, and leadership to mentor junior engineers while delivering back-end physical design for multi-die packages.

Qualifications

• BE/BTech or ME/MTECH with 15+ years of experience on high complexity SoC designs.
• Experience creating an IO ring in accordance with design specifications.
• Deep knowledge of ESD, latch-up, and other foundry requirements, as well as placement strategies.
• Hierarchical design implementation knowledge, including partitions/HMs/tiles push down to each core/tile.
• Understanding feed-through planning and implementation.
• PG creation and push-down methodologies.
• Understanding Analog components and their placement requirements according to design specifications.
• Demonstrating RDL knowledge and working with packaging for SoC floorplan design.
• PV clean-up on floorplan and ensuring self-derivation in all sign-offs, including Physical Verification, ESD, foundry/Analog requirements.
• Working knowledge of PnR implementation, physical verification, and STA.
• SoC RTL to GDSII implementation, with top level clocking strategizing and implementation.
• P&R flow owner which includes scripting and flow deployment for SoC & Blocks.
• In-depth knowledge of Physical Verification tools like Synopsys ICV & Calibre.
• Knowledge of Package PV checks, IO/Bump PV cleanup, PV rules viz. Antenna, Density, DFM, DFY, DPT at lower technology nodes 7nm or less.
• Led PV activities on SoC designs with expertise in DRC, LVS, DFM, HV checks and cleanup.
• Expertise in running PV checks on Flat/Hierarchical SoC designs with multiple power domains.

Responsibilities

• Hands-on SoC floorplanning, integration and P&R along with P&R Flow Development
• Establishes the integration plans for die with optimization for package and board constraints
• Bump planning, Die file generation, closing loop with package team on signal and power bump placement restrictions
• Create physical database for the IP or SoC. Collaborate with architects to optimize the placement of IPs for latency as well as die area/aspect-ratio
• Collaborate with the design teams on clocking and dataflow to deliver the physical block level floorplans for APR
• Derive specifications and collaterals for the IP blocks to execute the floorplan and automatic place and route (APR) at subsequent hierarchies
• Coordinate with power delivery team on trade-offs for metal allocation for signal and power
• Have excellent understanding on, die-per-reticle/good-die-per-wafer maximization, and right technology selection on metal layers usage maximization
• Performs integration of all dies in a package and completes the relevant checks before tape-out
• Supervise/lead/mentor junior team members.
