描述
If a user does not have a license for a licensed IP core, CORE Generator software should not allow the core customization GUI to open. However, for some cores a partial GUI is opening and if the user selects the "Finish" button, then the following message appears:
! Validation Failed: Error: It is not possible to generate this core without a valid license.
In the case of the LTE UL Channel Decoder, when no license is available, the following messages are displayed:

解决方案
The message is correct. The core cannot be generated without a license. However, in ISE 11.3 CORE Generator has been enhanced to make the generate option unavailable when a valid license is not found.
