Intelligent path planning method in digital twin environment

The invention relates to an intelligent path planning method in a digital twinborn environment. The method comprises the steps of determining a needed target area, obtaining satellite data of the target area and performing preprocessing, constructing a digital twinborn model of the target area, performing modeling by adopting a block modeling thought, and finally importing a deep learning model to obtain the digital twinborn model of the target area. Projecting a target area simulated by the digital twin model to a two-dimensional grid area; and projecting a real obstacle in the target area to the two-dimensional grid area, performing expansion operation on the obstacle, and if the projection of the obstacle crosses a plurality of grids, expanding the projection of the obstacle to all the crossed grids. An intelligent path planning plane algorithm A * is adopted, A * is embedded into the digital twinborn model, and a path corresponding to the minimum global cost F from the starting point to the target point is selected. Experiments prove that the path planned by the method provided by the invention is shortest in time consumption, so that the response efficiency of emergency departments for handling emergencies is improved.

Multi-instance block modeling for circuit component placement in integrated circuits

Aspects of the present disclosure provide for eliminating or reducing block uniqueness in a chip-level graph of a computer chip, reducing the size of the graph while still encoding block-specific information. For each group of blocks in the graph generated from a multiple instantiation block (MIB), a block in the group is selected as a base block. The physical location of the base block is encoded in the reduced graph, and the physical locations of the remaining blocks are encoded as linear transformations of the physical locations of the base block across the face of the chip. Each group of blocks instantiated from the same MIB is represented as a single instance. The reduced graph can be provided to a device configured to perform a circuit component placement process to identify placement of circuit components for blocks in the chip according to one or more objectives.
