Preventing interference between subsystem blocks at a design time

A non-transitory computer-readable storage medium comprising computer-executable instructions that, when executed by at least one processor, cause the at least one processor to:

• provide a user interface to generate a computerized graphical model representing a system, the graphical model including a plurality of subsystem blocks and a connection between a first subsystem block and at least one other subsystem block of the plurality of subsystem blocks;
• obtain an integrity level of the first subsystem block and an integrity level associated with the at least one other subsystem block;
• evaluate a predicted impact on an overall integrity level of the graphical model from a change to the integrity level of the first subsystem block, wherein the evaluation is based on the integrity level associated with the at least one other subsystem block;
• and
• determine whether to change the integrity level of the first subsystem block based on the result of the evaluation.

A computerized method comprising:

• providing a user interface to generate a graphical model representing a system, the graphical model including a plurality of subsystem blocks and a connection between a first subsystem block and at least one other subsystem block of the plurality of subsystem blocks;
• obtaining an integrity level of the first sub system block and an integrity level associated with the at least one other subsystem block;
• evaluating a predicted impact on an overall integrity level of the graphical model from a change to the integrity level of the first subsystem block, wherein the evaluation is based on the integrity level associated with the at least one other subsystem block;
• and
• determining whether to change the integrity level of the first subsystem block as a function of the result of the evaluation.

A non-transitory computer-readable storage medium comprising computer-executable instructions that, when executed by at least one processor, cause the at least one processor to:

• provide a user interface to generate a computerized graphical model representing a system, the graphical model including a plurality of subsystem blocks;
• obtain one or more integrity levels associated with at least some of the plurality of subsystem blocks;
• determine whether a first and a second subsystem block of the plurality of subsystem blocks interfere with each other;
• and
• when the first and the second subsystem blocks do not interfere with each other, execute the first and the second subsystem blocks in parallel.
