ID:21137 DELAY_CHAIN "<name> " which feeds the i input of IO_OBUF which feeds IO_PAD , which feeds IO_IBUF , which feeds DELAY_CHAIN primitive "<name> ", must have their delayctrlin fed by the same IO_CONFIG atom

CAUSE: The specified DELAY_CHAIN primitive , which feeds the i input of IO_OBUF that feeds IO_PAD, which feeds IO_IBUF, which feeds DELAY_CHAIN primitive, must have the delayctrlin fed by the same IO_CONFIG atom.

ACTION: Make sure that the delayctrlin input for the specified delay chains are fed by the same IO_CONFIG atom.
