na_0027: Use of only standard library blocks
Companies should specify a subset of Simulink® blocks for use when developing models. The block list can include custom block libraries developed by the company or third parties. Models should be built only from these blocks.
Non-compliant blocks can be used during development. If non-compliant blocks are used, they should be marked either with a color, icon and / or annotation. These blocks must be removed prior to use in production code generation.
