Job Description – AMS Layout Engineer
Job Title
AMS Layout Engineer
Experience
3–8 Years (can be adjusted based on hiring needs)
Location
Bangalore/Hyderabad
Job Summary
We are seeking a skilled AMS (Analog Mixed-Signal) Layout Engineer with hands-on experience in BCD technolgies with nodes in the range of 40nm to 180nm. The candidate will be responsible for implementing high-quality analog and mixed-signal layouts from schematics, ensuring compliance with design specifications, foundry rules, and signoff requirements.
The ideal candidate should possess strong expertise in floorplanning, layout execution, DRC/LVS closure, parasitic extraction, and post-layout support while collaborating closely with circuit design engineers throughout the development cycle.
Key Responsibilities
•Develop transistor-level and block-level Analog Mixed-Signal (AMS) layouts in SMOS10HV technology.
•Create and optimize floorplans considering performance, matching, area, routing, and reliability requirements.
•Translate sub-block schematics into physical layouts while maintaining the same hierarchy used in simulations.
•Implement layouts according to design documentation, layout guidelines, customer feedback, review comments, and back-annotation requirements.
•Ensure one-to-one correspondence between layout implementation and parameterized devices used in schematic simulations.
•Perform Design Rule Check (DRC) and resolve violations until achieving a clean signoff database.
•Perform Layout Versus Schematic (LVS) verification and resolve discrepancies until successful closure.
•Ensure compliance with all foundry-specific layout rules and process requirements.
•Generate extracted netlists and provide them to Design Engineers for post-layout simulation and back-annotation activities.
•Participate in layout reviews and implement corrective actions based on review findings.
•Maintain and update block review documentation with layout implementation details, observations, and recommendations.
•Work closely with circuit designers to optimize layout quality, performance, and manufacturability.
•Support tape-out activities and ensure timely delivery of layout milestones.
Required Qualifications
•Bachelor's or Master's degree in Electronics Engineering, VLSI, Microelectronics, or a related field.
•Hands-on experience in SMOS10HV process technology.
•Strong experience in Analog Mixed-Signal (AMS) Layout Design.
Good understanding of:
o Analog layout methodologies
o Device matching techniques
o Symmetry requirements
o Common-centroid layouts
o Interdigitated structures
o Guard rings and shielding
Experience performing:
oDRC
oLVS
oParasitic Extraction (PEX)
oLayout signoff activities
•Ability to interpret schematics and convert them into optimized physical layouts.
•Strong understanding of hierarchy-based layout implementation.
Preferred Skills
•Experience in:
oHigh-voltage analog layouts
oPower Management ICs (PMIC)
oAutomotive semiconductor products
oMixed-signal IP development
•Knowledge of ESD and latch-up protection concepts.
•Understanding of post-layout simulation methodologies.
•Familiarity with reliability and manufacturability requirements.
EDA Tools
Experience with one or more of the following:
•Cadence Virtuoso
•Mentor Calibre (DRC/LVS/PEX)
