Selected Research Directions
My lab explores ground-breaking data-driven EDA/AI methods to deliver better VLSI circuit design with lower NRE cost, less human effort, and shorter turnaround time. We view circuit as a special data type, then explore and utilize its unique data properties.
We are especially experienced in 1) early-stage circuit power evaluation, 2) early-stage circuit timing evaluation, 3) automated circuit generation, and 4) CPU prefetcher design.
