System Generator connects each open input port to a Xilinx® Constant Block. The new Constant blocks are set to the following default values:

Type: Signed (2’s comp)

Constant value: 0

Number of bits: 16

Binary point: 14

This terminate tool does not do data type checking on the input ports. If an open port requires a different data type, for example a Boolean data type, you will need to double-click the Constant block and change the Output Type to Boolean.

To check for data type mismatches, click the Simulink® model canvas, and enter Ctrl-D. System Generator will report on all the data type mismatches, if there are any.
