Can someone help me identify this circuit symbol please?
It is a link in the copper - not an actual component.
Also known as a &quot;net-tie&quot; (thanks @Spehro Pefhany)
It looks like it is from Cadence/Allegro.
The main value is that it allows nets of different names to be connected. Each of those names may have different attributes (eg trace width).
I used one today to force a trace to go to a specific place on a ground plane to avoid voltage drop affecting a sensitive analog measurement. Without this the source would have directly connected to the ground plane which could have had an additional voltage drop.
As noted by @le_top in the comments the &quot;Place Near&quot; attribute can be very useful in these situations.
