Use the Constant IP to tie signals up or down, and specify a constant value. The
Constant IP shows the constant value being driven by the block on the output pin. As an
example, the following constant IP shows a default value on the output pin
dout[0:0] being driven to 1.
To change the value double-click the IP. This brings the configuration dialog box as shown.
In this configuration dialog box, the width of the value to be driven is set to
5 (binary bits) and a value of decimal
30 is being driven. After the user commits to the changes,
the Constant IP shows the new values being driven on the output pin
Constant values can be set as decimal, hexadecimal or binary values. See the LogiCORE IP Constant Product Brief (PB040) for more information.
