Most I/O banks consist of 52 IOBs, although HR I/O mini-banks consist of 26 IOBs. The number of banks depends upon the device size and the package pinout. In the UltraScale Architecture and Product Overview (DS890) [Ref 3] , the total number of available I/O is listed by device type. This Figure is an example of a typical floorplan. The UltraScale and UltraScale+ FPGAs Packaging and Pinouts Product Specification (UG575) and Zynq UltraScale+ Device Packaging and Pinouts Product Specification User Guide (UG1075) [Ref 3] include information on the I/O banks for each device/package combination.
