However, leaving the guarantee of legality to an inexplicable neural network could be problematic in several applications. In this paper, we propose \\tool{DiffPattern} to generate reliable layout patterns. \\tool{DiffPattern} introduces a novel diverse topology generation method via a discrete diffusion model with compute-efficiently lossless layout pattern representation. Then a white-box pattern assessment is utilized to generate legal patterns given desired design rules.
