6.3 System Generator for DSP - How do I add a user-controlled enable to my HDL Blackbox, which I am importing to System Generator?

Description

General Description:

How do I add a user-controlled enable to my HDL Blackbox, which I am importing to System Generator?

Solution

You can add a user-control enable to a HDL blackbox by using a logical AND to combine the clock enable, that System Generator needs, with a user enable and then connecting that to the enable logic in your design. It is recommended that you name the user-control enable VIN so that the HDL parser does not confuse this enable with the clock enable that System Generator needs for its rate control.
