Job Title : IO Layout Engineer
Experience : 3+ Years
Location : Bangalore
Employment Type : Full-time
Industry : Semiconductors / ASIC / VLSI / IO & ESD Design
Job Summary :
We are looking for a highly motivated and experienced IO Layout Engineer to join our custom layout team. The candidate will be responsible for full-custom layout of IO cells, ESD protection structures, and high-voltage interfaces for ASIC / SoC applications in deep submicron and FinFET technologies.
Key Responsibilities :
- Perform transistor-level custom layout of various types of IO cells including :
- Standard IOs (CMOS, LVTTL, LVCMOS, SSTL, HSTL)
- High-speed and specialty IOs (DDR, USB, PCIe, HDMI, etc.)
- ESD structures, pad rings, and protection circuits
- Work closely with IO circuit designers to interpret schematics and design intent.
- Ensure robust layout practices for :
- ESD compliance
- Latch-up prevention
- Electromigration (EM)
- Voltage isolation and guard ring planning
- Ensure layout meets foundry-specific DRC, LVS, and antenna rules.
- Run and close physical verification (DRC, LVS, ERC, ANT) using industry-standard tools.
- Participate in floorplanning of IO ring and integration with analog / digital blocks.
- Coordinate with packaging, ESD, and reliability teams to support silicon tapeout.
Required Skills and Experience :
B.E / B.Tech or M.E / M.Tech in Electronics, Electrical Engineering, or VLSI.3+ years of hands-on experience in IO and / or ESD layout.Strong understanding of ESD protection concepts and latch-up avoidance.Expertise in Cadence Virtuoso for layout design and implementation.Experience with DRC / LVS tools (Calibre, Assura, PVS).Familiarity with advanced process technologies (28nm, 16nm, 7nm, FinFET, etc.).Good knowledge of layout-dependent effects (LDE), IR drop, and reliability constraints.Attention to detail and strong debugging / problem-solving skills.Preferred Qualifications :
Experience in high-voltage or multi-voltage IO layout (1.8V / 3.3V / 5V interfaces).Experience with IO ring planning and integration in complex SoC floorplans.Familiarity with power grid design, bump / ball map coordination, and ESD co-design.Scripting experience in SKILL, Tcl, or Python for layout automation.Interested can share Cv to Sharmila.b@acldigital.com
