  • Patent number: 11347924
    Abstract: A chip layout method based on a minimum total wire length, includes: initializing a total wire length to a preset value, initializing a number of iterations, randomly generating a sequence pair to represent a positional relationship between rectangular circuit modules, inputting the sequence pair to a model, and solving to obtain a sequence pair having a minimum wire length within the number of iterations; changing a field operator of the sequence pair to obtain a new one, inputting the new sequence pair to the model, retaining, if an obtained total wire length is less than the original total wire length, the new sequence pair, or otherwise, abandoning the new sequence pair; repeating the above operation till the number of iterations is reached; and outputting a minimum total wire length, and coordinates of each rectangular circuit module to obtain the chip layout based on the minimum total wire length.

  • Patent number: 11176290
    Abstract: Disclosed is an approximate physical simulation integrated debugging method based on digital twinning, which includes the following steps of: a production line simulation model building step, a twinning step, a system debugging step, a hardware-in-the-loop debugging step, and a device-in-the-loop debugging step. The approximate physical simulation integrated debugging system based on digital twinning includes a production line simulation model building module, a twinning module, a system debugging module, a hardware-in-the-loop debugging module, and a device-in-the-loop debugging module. According to the approximate physical simulation integrated debugging method and system based on digital twinning, since a local component twin after being successfully debugged is replaced with an entity component, when a problem occurs after replacement, only the local component twin needs to be debugged and optimized again, thus saving time and reducing cost.
