AI Technical Summary

Problems solved by technology

[0003] At present, the design of the navigation microsystem is usually after the completion of the design of each sub-module, and then the integrated simulation is carried out in a unified way. There is a lack of integrated design technology for the composite navigation microsystem, and the system integrity cannot be guaranteed before the process is manufactured, nor can it achieve high confidence. design optimization

Moreover, there are differences in tool types and versions in the existing platforms of relevant designers, and it is difficult to share data interactively. The research and development costs are high and difficult, and product development often requires multiple iterations, resulting in low efficiency in microsystem design. The cycle is long, which affects the development progress and efficiency of the system
