Good knowledge on Physical Design flow,from RTLto GDSII.
Good at Floor Planning, Placement, CTS and Routing techniques, debugging block level issues and any flow related issues.
Implemented block level automated methodology flow setup, enhancing design efficiency and reducing manual intervention
Experienced in Fixing Basic DRC/LVS & Clearing shorts
Good at writing scripts using TCL , Python, AWK and SED.
I have worked 1 year 1 months as a google app store application reviewer.
Key Responsibilities:
• Hands-on training in ASIC physical design flow using industry-standard EDA tools.
• Gained expertise in floorplanning, placement, clock tree synthesis (CTS), routing, and signoff.
• Worked on real-time projects to understand design challenges and optimization techniques.
• Exposure to industry best practices for DRC, LVS.
Key Responsibilities:
Roles and Responsibilities:
• Block level PnR, ECO implementation & final verification.
• Handling all block level issues including PV to achieve Quality Tape out.
• Completed 2 Tape outs in currently working on two Project in PnR implementation.
Challenges:
Project-IV Handling Block level PnR implementation from Floorplan to Signoff, 4 nm technology, 1.2GHz frequency.
Project (Polaris B0)
Tool Innovus
• Presently working on setting up block level flow flush with the floorplan creation for the latest released input collaterals and making runs with different recipe settings for achieving optimized results.
• Analyzing flow setup and runs QoR results.
• Working with constraint updating, as lot of constraints and clock grouping definitions are missing in the SDC.
Project-III: Worked on flow setup for make Edition2.0 Block level PnR implementation flow from Floorplan to Signoff
Project (PnR EDISION2.0 FLOW)
Tool - Innovus
• Working closely with the new Edision2.0 flow. Flow was basically having some automated feature compared to the previous make flow.
• working on setting up block level flow flush. Updating for every stage from Floorplan to Signoff.
Project-II: Handled a block of 3 nm technology, 1.5 M instruction count, 3 GHz frequency. Worked on setting up the PnR to GDS flow.
Project (SMSM)
Tool - Innovus
• Working closely to PnR flow and also on CTS to fix latency issues. Placed Clock Root Buffers manually to fix latency issues.
• I have done custom placement for data pat-hand clock path for critical path as frequency is high.
• Manually routed a lot of nets in critical path in high layer to fix setup violations.
• Had to do lot of manual work with skewing techniques for setup and avoiding IR & DRC critical areas.
• Developed basic RM flow from floorplan to Sign-Off Gds.
Project-I: Handled a block of 5 nm technology, 1.2M instance count, and 3.2 GHz frequency.
Project (SAINTL)
Tool - Fusion Compiler
• Working closely with design team giving proper feedback Macro placement and other checks reports for better convergence.
• Analyzing different issues seen at each stage during PnR and working out solutions to create best recipe.
• Tried different techniques in ECO phase to reduce DRC’s and shorts in routing critical regions like downsizing/deletion of non-critical cells, spreading cells and manual-routing and manually moving-some cells in congestion critical area to non-critical area.
