Abstract: A rectilinear-block placement method includes disposing a first sub-block of each flexible block on a layout area of a chip canvas according to a reference position, generating an edge-depth map relative to first sub-blocks of flexible blocks on the layout area, predicting positions of second sub-blocks of the flexible blocks with depth values on the edge-depth map by a machine learning model, and positioning the second sub-blocks on the layout area according to the predicted positions of the second sub-blocks of the flexible blocks.

Abstract: A neural network based method places flexible blocks on a chip canvas in an integrated circuit (IC) design. The neural network receives an input describing geometric features of a flexible block to be placed on the chip canvas. The geometric features includes an area size and multiple aspect ratios. The neural network generates a probability distribution over locations on the chip canvas and the aspect ratios of the flexible block. Based on the probability distribution, a location on the chip canvas is selected for placing the flexible block with a chosen aspect ratio.
