I want to use IOBUFDS to receive differential inputs. Here is how i defined it:
Here is how vivado interpreted in schematic:
The error says that IOBUFDS_0/IO has multiple drivers, one is LA01_data_in_p, another OBUFTDS/O. In the RTL, I set T=1, why OBUFTDS/O is connected to the IO port?

@muzaffer We also tried IBUFDS and it doesn't fit our design, so we want to configure the IOBUFDS to be equivalent to IBUFDS to see what happened. I am just wondering why this kind of configuration for IOBUFDS has problem or IOBUFDS doesn't support T=1 in Ultrasacle?
Here is IBUFDS schematic we used:

What do you mean by "it doesn't fit our design" ?
