Depending on the purpose, the Engee blocks represent various components of the system, their interaction and behavior.

The term in Russian: Code generation

Definition: The process of automatic generation of executable program code in the C language. Instead of the user developing the necessary code himself, code generation allows you to create code automatically for further integration into a user project.
