Create Pcell to generate schematic-driven layout in Cadence Virtuoso-XL and EDA scripts in Cadence skill, ROD, and Perl. Develop DRC, LVS, and parasitic extraction runset files in Calibre and Assura.

Implemented Netlist to GDS of digital designs. Completed floor planning and partitioning, synthesis, formal verification, place and route, clock tree synthesis, signal integrity analysis and timing closure with different process nodes of 14nm, 16nm and 28nm .

Developed and implemented plans to synthesize, implemented including Design-For-Test (DFT) and close timing on complex digital integrated circuits at the block level (100K to 1M+ gates) which are coded in VHDL/Verilog .

Designed, implemented and maintained synthesis, DFT and Static Timing Analysis scripts using best-in-class methodologies Extensive experience in static timing analysis, power and noise analysis and back-end verification across multiple projects .

Analyzed log and report files to ensure the tools are getting the required results and make adjustments to the scripts to get the required results within the scheduled milestones . with backend design EDA tools Synopsys or Cadence .

Experienced in Design-For-Test tools & methodologies (Scan chains, ATPG, BIST, Fault models, Fault Coverage and generation). Experienced with Verilog/VHDL and Digital Design Principles .

Worked with various design groups across different disciplines (Logic, Circuits, DFT & Layout) to meet timing closure, area, power, and performance requirements .

Successfully track records of taping out complex SOC in 16nm and beyond . Working knowledge of deep sub-micron routing issues as they relate to power and timing .

Strong scripting skills in Perl, TCL and Shell, particularly in synthesis & timing analysis . Communicated regularly with the project teams world-wide to resolve issues and to ensure meeting targeted goals and schedule .

Ported / migrated design from one technology node to another by creating database (layout and schematic) translation/migration tools using Cadence skill.

Provided quality PDKS in timely manner and improved design efficiency without silicon respin by instituting robust test / validation methodologies for custom / foundry PDKs and installing, developing, validating, updating, and maintaining all RF / analog custom and foundry PDKs, standard cell and I/O libraries with different process nodes of 14lpprf, 14lpcrf, 16ff, 28nm, 65nm, 150nm and 180nm.

Developed new tools and methods to further automate commercial tools by creating configuration file, GUI, and essential functions for R3D/RMAP, schematic design capture, ADE/ADEXL simulation (Spectre, AMS, bda, Golden Gate), layout tools such as skillCAD, VXL schematic to layout device placement, Calibre/Assura DRC, LVS, xRC, and LPE back annotation.

Constructed high-performance custom devices, inserting into custom libraries and enabling necessary views for simulation, layout, physical verification, and parasitic extraction. Saved money on Assura licenses by generating CAD automation scripts for Metal/Poly fill, Metal slot, XOR, and ANTENNA tool.
