1. A method for model-based generation of startup configurations of embedded systems, comprising: importing an embedded system first startup configuration in textual representation into a modeling module by a system synchronization module; generating a graphical representation configured as a program flowchart of the first startup configuration by the modeling module; modifying the graphical representation of the first startup configuration by editing graphical elements and their respective connections in the modeling module that creates a modified startup configuration by editing the graphical representation of the first startup configuration; generating a second, modified startup configuration in textual representation from the modified graphical representation by the modeling module; testing and validating an actual behavior of the embedded systems at startup of the embedded system by a validation module making a comparison with the second startup configuration of respective textual representations; and exporting the second, modified startup configuration into the system synchronization module.
