Abstract
Description
Technical Field
[0001] The present invention relates to a scene modeling method and system for storage chip preparation, belonging to the technical field of storage chips. Background Art
[0002] With the development of chip manufacturing technology and 5G technology, the quality requirements for the prepared memory chips are gradually increasing. For example, there are high requirements for the thermal stability and electrical signal stability of memory chips. However, the existing technology in memory chip preparation still cannot keep up with the quality requirements for memory chip preparation.
[0003] At present, some solutions use scenario modeling and simulation to simulate various parameters of the memory chip that is about to be put into use. Scenario modeling refers to the process of abstracting the operation logic of various parameters of the memory chip during operation into a mathematical model, and simulation refers to the process of simulating the operation logic of various parameters of the memory chip during operation. Both are processes of describing the operation logic of the memory chip. However, whether it is the former or the latter, in the prior art, most of them model the memory chip as a whole, and do not model the various parts inside the memory chip. For example, when the memory chip is installed on a certain device A, the prior art models the electrical signal, temperature and other data of the memory chip as a whole on the device A, and there is no solution that can model the various parts inside a single memory chip. Secondly, the memory chip is the result of circuit integration and must contain a large number of electronic devices. If these large numbers of electronic devices are modeled one by one, the modeling workload will be huge. Therefore, a solution is urgently needed to refine the scenario modeling while reducing the workload of scenario modeling. Summary of the invention
