block_interface

Defines the contract for all logic blocks in the safety analysis.

BlockInterface

Bases: ABC

Abstract interface defining the mandatory structure for all logic blocks.

Every block in the system must implement this interface to ensure modularity and nesting capabilities within the safety analysis.
