 This repository contains the benchmark for the decoupling capacitor placement problem (DPP) and the accompanying paper "DevFormer: A Symmetric Transformer for Context-Aware Device Placement". The benchmark is designed to evaluate the performance of the proposed DevFormer architecture and to facilitate future research in hardware design optimization.
