DCI Cascading - Can there be more than one master bank in a column?


Can there be more than just one master bank in a column?


Yes, there can be more than one master/slave combination per column.

There needs to be a DCI_CASCADE XDC/UCF constraint for each master/slave grouping. 

For example, for a given device, if banks 11, 12, 13, 14 , and 15 are adjacent banks in one column and banks 11, 12 and 13 are compatible (meaning they have the same VCCO, VREF and adhere to DCI I/O banking compatibility rules), but banks 14 and 15 do not (but are compatible with each other), then banks 11, 12 and 13 can be one master/slave grouping and banks 14 and 15 can be another master slave grouping.


set_property dci_cascade {11} [get_iobanks 12 13]
set_property dci_cascade {14} [get_iobanks 15]


CONFIG DCI_CASCADE = "11 12 13";
