Abstract

We introduce a sub-millisecond thermal floorplanner based on High-Energy Cascade Physics (Bhabha Theory). Unlike standard diffusive FEA solvers, the "Thermal Sieve" accounts for ballistic phonon transport at the 1nm scale, correcting industry-standard temperature underestimations by up to 48.5°C in multi-tier architectures.
