High Speed SelectIO Wizard - Data width range not updating currently when sharing a bank between 2 interfaces

Description

If you are using the High Speed SelectIO Wizard to generate 2 Interfaces within one bank (i.e. Set number of interfaces = 2), the Bus data width can be set to 23 for both interfaces if you select the Bank values after you set the Bus data width. 

However, this results in an error message saying "Two interfaces in the same bank exceeds the IO limit per bank".

The widths should be dynamically updating to the maximum number of IOBs available in the banks.

This is working correctly if the same banks are selected first; checking the data widths, the range is correctly updated as [1-15].

Solution

The data widths will update correctly if you select the Bank values in the Pin Assignment tab first and then go bank to the Interface Settings tab.
