In my design, the single-ended input port "AA" only drives one register "AA_reg" and an IOB TRUE property is added on the port.
set_property IOB true [get_ports AA]
During place_design, the following error occurs and the register cannot be placed properly:
How can I resolve this issue?
This issue is fixed in Vivado 2015.3.
To work around the issue, you can apply the IOB=TRUE property to the register instead of the port.
set_property IOB true [get_cells AA_reg]
