Description

Technical Field

[0001] The present invention relates to the field of digital twin technology, and in particular to a digital prototype RAM deployment and operation method and system. Background Art

[0002] In the traditional field of digital prototyping, a series of complex steps are usually required to enable an application to run properly on the target platform. First, developers need to write application code, which is the core part of implementing specific functions. Next, the application needs to adapt to the operating system to ensure that the operating system's resources and services can be effectively utilized.

[0003] In order for the application to run correctly on the digital prototype, the developer needs to compile and package the application code, necessary operating system components, and all related files in the MSL project. This process usually involves using specific build tools and scripts to generate an executable application package. Once packaged, the package can be installed on the target system, allowing the application to run in the digital prototype environment.

[0004] However, this traditional packaging method has obvious disadvantages. Every time the application needs to be modified, such as fixing a bug or adding new features, developers must re-execute the entire compilation and packaging process. This means that even the smallest change requires building the entire application package from scratch. Such a process is not only time-consuming, but also inefficient, especially when the project becomes more and more complex, the time required for each packaging will increase accordingly. In addition, frequent packaging may also lead to challenges in version control and testing, because each packaging needs to ensure that the new version can run correctly and without errors.

[0005] Therefore, this traditional packaging method may cause considerable trouble to the development team in actual applications, especially in a development environment with rapid iterations and frequent updates. Summary of the invention
