Job Summary

We are looking for a skilled Physical Design Engineer to support end-to-end ASIC/SoC implementation from netlist/RTL to GDSII . The engineer will be responsible for physical implementation, timing closure, PPA optimization, physical verification, and sign-off while working closely with RTL, synthesis, STA, DFT, and verification teams.

Key Responsibilities

• Execute the complete physical design flow:
• Floorplanning
• Power planning
• Placement
• Clock Tree Synthesis (CTS)
• Routing
• Optimization
• ECO implementation
• Physical sign-off
• Perform Static Timing Analysis (STA) and resolve setup, hold, transition, and clock violations.
• Analyze and optimize timing, power, area, congestion, and signal integrity .
• Work on MMMC (Multi-Mode Multi-Corner) implementation and timing closure.
• Develop and review timing constraints, including SDC, clocks, generated clocks, and timing exceptions .
• Perform physical verification and sign-off activities including DRC, LVS, antenna, EM/IR, and power integrity checks.
• Debug placement, routing, congestion, timing, and physical-design violations.
• Collaborate with RTL, synthesis, STA, DFT, power, and verification teams to achieve project milestones.
• Support tape-out activities and ensure design quality meets performance, power, area, and reliability targets.
• Develop and improve implementation flows using Tcl/Python/Perl/Shell scripting .
• Participate in methodology development and automation initiatives.

Required Technical Skills

• Strong understanding of ASIC/VLSI Physical Design flow from RTL/Netlist to GDSII .
• Good knowledge of:
• Floorplanning
• Placement
• CTS
• Routing
• Timing closure
• ECO
• Physical verification
• Power planning
• Strong understanding of setup/hold timing and STA .
• Knowledge of MMMC analysis and timing constraints .
• Experience with industry-standard EDA tools such as:
• Cadence Innovus
• Synopsys ICC2/Fusion Compiler
• Synopsys PrimeTime
• Cadence Tempus
• Calibre/ICV
• Scripting knowledge in Tcl, Python, Perl, or Shell .
• Understanding of DRC, LVS, EM/IR and power integrity is preferred.
• Exposure to low-power design/UPF and advanced technology nodes is an advantage.

Education

• B.E./B.Tech/M.E./M.Tech in Electrical Engineering, Electronics & Communication, VLSI, Microelectronics, or a related field .
