after grouping the searched networks is completed, updating the values of variables in the search terms, and returning to execute the searching of the networks with the network names containing the search terms in the range of the printed circuit board until the corresponding networks cannot be searched.
7. The apparatus according to claim 6, wherein the network grouping unit is specifically configured to:
distributing the network with the network name containing the search word and the preset control group network identifier to the corresponding control group of the double-rate synchronous dynamic random access memory;
and distributing the network with the network name containing the search word and not containing the preset control group network identification to a plurality of data groups of the corresponding double-rate synchronous dynamic random access memory.
8. The apparatus of claim 5,
the instruction analysis unit is also used for analyzing the manual grouping instruction under the condition of receiving the manual grouping instruction to obtain a network name to be distributed and a target double-rate synchronous dynamic random access memory name;
the network grouping unit is further configured to allocate the network corresponding to the network name to be allocated to the double-rate synchronous dynamic random access memory corresponding to the target double-rate synchronous dynamic random access memory name.
9. A storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the double data rate synchronous dynamic random access memory grouping method of any one of claims 1 to 4.
10. A processor comprising a memory and a processor, wherein the memory is configured to store program instructions;
the processor is used for executing the grouping method of the double-rate synchronous dynamic random access memory according to the program instructions stored in the memory, wherein the grouping method of the double-rate synchronous dynamic random access memory is as claimed in any one of claims 1-4.
