This invention proposes a chip standard cell legalization method and system considering the adjacency diffusion effect, relating to the field of electronic design automation. The specific scheme includes: constructing a minimum spanning tree based on cell layout and left / right diffusion height; decomposing and reconnecting the minimum spanning tree to generate Hamiltonian paths; calculating the cell's station position on the layout row according to the vertex order in the Hamiltonian path and the cell width; and designing an algorithm based on Hamiltonian completion to calculate the new cell position. By moving cells on a single layout row to make adjacent cells have the same diffusion height, this reduces NDE violations to near-optimal minimum and minimizes maximum cell movement without any area overhead, while achieving better actual runtime.
