Error(17044): Illegal connection on I/O input buffer primitive u31dc_0|u31pipe_0|u31ddiorx|gpio_0|core|gpio_one_bit.i_loop[23].altera_gpio_bit_i|input_buffer.ibuf. Source I/O pin u31dc_0|u31pipe_0|pipe_rx_phy[23] drives out to destinations other than the specified I/O input buffer primitive. Modify your design so the specified source I/O pin drives only the specified I/O input buffer primitive.
This error message indicates that the IP's input pin is connected to somewhere else instead of buffer. Can you check your design?
Thank You
