This block is listed in the following Xilinx® Blockset libraries: Basic Elements, Data Types, and Index.

The Xilinx Concat block performs a concatenation of n bit vectors represented by unsigned integer numbers, for example, n unsigned numbers with binary points at position zero.

The Xilinx Reinterpret block provides capabilities that can extend the functionality of the Concat block.

Block Interface

The block has n input ports, where n is some value between 2 and 1024, inclusively, and one output port. The first and last input ports are labeled hi and low, respectively. Input ports between these two ports are not labeled. The input to the hi port will occupy the most significant bits of the output and the input to the lo port will occupy the least significant bits of the output.

Block Parameters

The block parameters dialog box can be invoked by double-clicking the icon in your Simulink® model.

Parameters specific to this block are as follows:

  • Number of Inputs: specifies number of inputs, between 2 and 1024, inclusively, to concatenate together.

Other parameters used by this block are explained in the topic Common Options in Block Parameter Dialog Boxes.

The Concat block does not use a Xilinx LogiCORE™.
