Job details:
• Role Level: Lead Full-Time
• Location: Vijayawada / Hybrid (Flexible)
• Experience: 4+ years in Full-Custom AMS Physical Layout & Multi-Foundry Physical Verification
Role Overview:
Own end-to-end physical implementation: full-custom analog layout, automated digital place-and-route,
full-chip (analog + digital) integration, foundry PDK bring-up, power grid synthesis (PDN),
electromigration/IR-drop analysis, and DRC/LVS sign-off on advanced nodes — bringing 100% of the
tape-out physical design flow in-house without reliance on an external design partner.
Key Responsibilities:
• Foundry PDK Setup & Customization: Install and verify foundry PDKs, techfiles, cds.lib, display.drf,
layer maps, and symbol libraries for custom physical design.
• Floorplanning and full-custom physical layout of fine-pitch sensor pixel arrays, high-speed column
SAR ADC banks, bandgap references, and I/O pad rings on advanced nodes.
• Multi-Vendor Physical Verification Sign-Off: Execute golden DRC, LVS, ERC, Antenna, and DFM
physical verification using Siemens Calibre Interactive / RVE and Synopsys IC Validator (ICV),
ensuring zero DRC/LVS violations prior to tape-out.
• Perform parasitic extraction (PEX / xACT / xRC) and generate clean Calibre/ICV runset reports
and extracted netlists for post-layout SPICE re-simulation.
• Execute Power Distribution Network (PDN) routing, dynamic IR-drop analysis, electromigration
(EM) checks, and substrate noise isolation.
• Implement active metal shielding, ESD protection clamps, and anti-tamper physical layout
structures to ensure robust physical integrity.
• Own foundry PDK bring-up and technology file installation, corner library validation, and DRC/LVS
rule deck qualification for each new process node or PDK revision — the hands-on execution layer
beneath the Chief Silicon Architect's PDK customization oversight.
• Administer the team's core EDA license server (FlexLM/FlexNet) and keep Cadence, Siemens
Calibre, and Synopsys tool installs current — a lightweight collateral duty at this team size (single
license manager and shared design server, not a dedicated compute grid).
Qualifications & Technical Skills:
• B.Tech / M.Tech in Electronics / VLSI Design or equivalent industry experience.
• 4+ years of hands-on expertise in full-custom Analog/Mixed-Signal physical layout and tape-out
sign-off.
• Experience in layout automation using SKILL / Python / TCL scripting and Parameterized Cells
(PCells) for array generation.
• Deep mastery of Siemens Calibre (Calibre DRC, Calibre LVS, Calibre PEX, Calibre DFM) and Calibre
RVE debugging workflows.
• Working familiarity with Synopsys IC Validator (ICV) and Cadence Pegasus / Quantus toolchains.
• Mastery of Cadence Virtuoso Layout XL / GXL and parasitic extraction flows.
