I want to use I2C Bus as shown in the figure enter image description here

my question is how should I name the Bus itself the problem that I have that Net labels as shown in the doc like LED0 LED1... which would mean that bus name LED[0..9].

thanks for any hint !

You can do that by writing the name like this:


Then when you label the BUS it will appear "BUSNAME" and not all the signals.

  • \$\begingroup\$ This does not seem to work in Altium 17.1; BUSNAME:A[1..10],B,C shows up as exactly that entire text, and hovering over the bus just shows the net name as "BUSNAME:A[1..10]" (without B or C) \$\endgroup\$

The Altium concept of busses differs from Mentor or other CAD systems. In Altium a bus is a bundle of nets following the same naming pattern : "[Name][NumericalIdentifer]" Example: ADDR0, ADDR1, ADDR2 ... etc. can enter the bus ADDR[0..n]


For your purpose you have to use harnesses as you did in your schematic. This concept can group nets with different net labels following no naming pattern.
