Just a CAD tool survey... Is there a tool that understands that there
can be a line on a power net that's actually meant to not connect to
any other part of the same net? (except on the pin of the sense line)
I use Allegro and I manually add no_shape_connect properties to vias
so that the sense line can route back to the supply without shorting
to the power plane. This seems silly.
Sense lines function on the basis of current flow through differing
micro-impedance tracing. This can be simplifiedfor CAD by introducing
an identifiable component, be it a low value resistor, link or other
physical object.
As practical remote sense lines may need an alternate remote
connection point, this isolating lower-impedance element is often
required anyways as a 'default' connection, in the event of an
open-circuit remote connection.
