Abstract: The existing problems of simulation models for different experiments are studied in the paper. Aiming at the problems related to the simulation model data and experimental design, a database for connector calls based on the design parameter matching is established. Based on the model requirements of the database framework, an integrated evaluation framework is established. There are interfaces for the expansion of the database, and the missing models of the database are filled in time to meet the integrity requirements of the experimental design evaluation. The system performance index based on safety margin can provide overall safety margin and improve the efficiency and safety of test design.
