Sub ID Recommendations

  • NA-MAAB — a

  • JMAAB — Not supported

MATLAB Versions



Sub ID a

Control algorithm models shall be designed from discrete blocks.

Scope and Display blocks can be used in the model diagram.

These sink blocks shall not be used:

Consider using signal logging and the Viewers and Generators Manager for data logging and viewing requirements. (R2019b and later) To log and manage the signal, click the Simulation tab and, under the Prepare gallery, select the appropriate tool.

Custom Parameter

Not Applicable


Sub ID a

  • Improves readability and model simulation.

  • Code generation may not be possible.
