Experience

Physical Design & STA Engineer

End-to-end ASIC implementation from netlist to GDSII across 130 nm and 22 nm to 7 nm, with a strong background in timing-driven closure, MMMC analysis and physical verification.

Skilled in floorplanning, placement, clock tree synthesis, routing and signal integrity analysis.

Hands-on experience with timing closure, ECO implementation and congestion optimization, and with automating design flows in TCL and Python.

Founder and technical lead of a RISC-V initiative focused on microarchitecture development and ASIC implementation with open-source EDA flows. Research experience includes radiation effects, fault-tolerant design and circuit-level reliability analysis in advanced FinFET technologies.

Across the backend flow

The pieces of the flow I own, from constraints to signoff.

01

SDC

Definition and validation of timing constraints for complex ASICs (clocks, exceptions, IO) for accurate STA and closure across MMMC scenarios.

02

UPF

Low-power implementation with UPF: power domains, isolation strategies, level shifters and power-intent verification.

03

Floorplanning

Macro placement, power grid design and congestion-aware partitioning for optimal performance, power and routability.

04

Place & Route

Full PnR from synthesized netlist to tapeout, including placement, CTS, routing and physical optimization.

05

STA

Static timing analysis and closure using MMMC methodologies: setup/hold fixing, ECO implementation and timing-driven optimization.

06

DRC / LVS

Physical verification and signoff with DRC, LVS, antenna and density checks for advanced-node manufacturability.
