The attached PLECS Standalone model contains a custom subsystem developed to behave as an 8-to-1 multiplexer or data selector. The block takes 8 signals as inputs and using three select signals routes one of the inputs to the output. The implementation is open to the user (Ctrl+U) and can help to show how other types of multiplexer logic can be designed.
