As shown in This Figure, banks 88, 89, and 90 in the XCZU11-FFVB1517 device connect to the same pins as banks 90, 91, and 93 in the XCZU17-FFVB1517 and XCZU19-FFVB1517 devices. This Figure and This Figure show how the banks are arranged on each particular device. For the XCZU11, the banks are contiguous and could support a three-bank interface that requires the banks to be contiguous. However, the three banks that connect to the same pins on the XCZU17 and ZXCU19 are not contiguous, and this might result in timing differences and possible design rule issues for interfaces that require the banks to be contiguous, such as memory interfaces.
