Abstract: Provided are a chip and a pin line-out design method therefor, which are applied to a BGA packaged chip. The method includes: according to pin position information and pin definition information of a chip, determining a number of circuit board layers required for pin line-out of the chip (S1); allocating line-out layers to pins of the chip in their respective circuit boards (S2); and according to a pin density and transmission line width requirement of the chip, determining a specification of a via hole in each circuit board for leading the pin of the chip out to the corresponding line-out layer, to perform a corresponding line-out design on the basis of the via hole (S3). It may be seen that the described unified pin line-out design for the BGA packaged chip is more refined, and the quality of the line-out design of the pins of the chip is ensured.

Abstract: Disclosed in the present application are a battery charging method and apparatus, and a device and a medium. The method includes; collecting, at a preset time interval, battery charging state data of a rechargeable battery within each of the preset time intervals in real time; when the battery charging state data within any one of the preset time intervals is collected, using the battery charging state data within the preset time interval as a training data set, inputting the training data set to an initial neural network model for training, and during the process of training, updating a preset network parameter on the basis of the difference value between a model output value corresponding to each piece of battery charging state data and a preset threshold until difference value between model output value corresponding to present battery charging state data and the preset threshold meets a preset error condition.
