So, if I put nets together with my components, and then switch to
layout editor, isn't the program supposed to logically come up with a
layout?
In my schematic, I connected the components together using these
"buses" and then some pop up error came up and said that they need to
be connected using nets. So I put the nets on top of the busses, is
this right? Or do I only need nets OR busses?
Thanks,
Tei
