7 Series SelectIO - DCI Cascade usage across 7 Series devices

Description

The DCI Cascade (DCI_CASCADE) constraint identifies a DCI master bank and its corresponding slave banks, and can be used for Virtex-5, Virtex-6 and for 7 Series devices that have High Performance (HP) banks available. High Range (HR) banks do not have DCI available and use the IN_TERM constraint, while HP banks do have DCI available. This is why the DCI Cascade constraint can only be applied to HP banks.

Solution

The Constraints Guide (UG625) does not list 7 Series as supported devices for using the DCI_CASCADE constraint. This is incorrect and will be addressed in a future release of the Constraints Guide. Please refer to UG625 for usage and syntax examples as these are still applicable to 7 Series devices in HP banks only.
