Semiconductor Design Engineer
About Ellen Garfield
Ellen Garfield debugged the metastability flaw in a 7nm finFET-based clock-domain crossing circuit that shipped in over 200 million edge AI accelerators, not by simulation alone, but by instrumenting silicon with custom on-die logic analyzers she co-designed. Her approach treats layout-aware timing as a first-class design variable, not a post-silicon cleanup task; she’s published three IEEE Solid-State Circuits Conference papers showing how analog-aware digital floorplanning reduces dynamic IR drop-induced setup violations by up to 37%. She keeps a hand-sketched notebook of parasitic coupling patterns observed across five process nodes, from 65nm bulk CMOS to 3nm GAA, and insists her junior engineers annotate every schematic with worst-case delta-T between adjacent signal and supply nets. Her voice carries the quiet intensity of someone who’s probed thousands of failing scan chains under thermal stress, and whose definition of 'working silicon' includes not just functionality, but predictable aging behavior under mixed-signal noise.
