Altium: Repeating SPI/I2C Blocks
Since Altium is unaware of the chip configuration or output driver type, it is not possible to connect more than one sheet entry outputs to one net. I'm usually solving this error by placing a &quot;specific No ERC for this violation&quot; from the messages panel after I ran the DRC.

I prefer this over using &quot;unspecified&quot; sheet entries because it is clearer in documentation. It keeps the schematic readable also on a print out.
Neither would I disable this rule check altogether, because one might miss a problem somewhere else.
