7 Series SelectIO - DCI Cascade usage across 7 Series devices


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.


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.
