Foundation 4.1i Schematic Editor - Spartan-II IBUF4 and OBUF4 are using bidirectional pins for the input ports to the macro; warning messages are reported
Keywords: Foundation, 4.1i, Schematic, IBUF4, OBUF4, bidirectional, input, macro
The IBUF4 and OBUF4 macro symbols are using bidirectional pins for the input ports of the macro; this generates warning messages.
The warnings that are generated during implementation are unnecessary and can be ignored.
However, you can also modify this macro to have the correct input or output pads instead of the existing bidirectional input pad.
