Introduction to Simulink with Engineering Applications

Chapter 13: The Signal Routing Library

Overview

This chapter is an introduction to the Signal Routing library. This is the twelfth library in the Simulink group of libraries and consists of two sub-libraries, the Signal Routing Group Sub-Library, and the Signal Storage & Access Group Sub-Library blocks shown below. We will describe the function of each block included in this library and we will perform simulation examples to illustrate their application.

13.1 Signal Routing Group Sub-Library

The Signal Routing Group Sub-Library contains the fifteen blocks described in Subsections 13.1.1 through 13.1.15 below.

13.1.1 The Bus Creator Block

The Bus Creator block combines a set of signals into a group of signals represented by a single line. This block is described in Section 2.6, Chapter 2, Page 2 7.

13.1.2 The Bus Selector Block

The Bus Selector block outputs a specified subset of the elements of the bus at its input. This block is described in Section 2.6, Chapter 2, Page 2 7.

13.1.3 The Bus Assignment Block

The Bus Assignment block assigns values, specified by signals connected to its assignment (:=) input ports, to specified elements of the bus connected to its Bus input port. We use the block's dialog box to specify the bus elements to be assigned values. The block displays an assignment input port for each bus element to be assigned a signal.

In the Function Block Parameters dialog box, the Signals in the bus displays the names of the signals contained by the bus at the...
