I have I have a current sense shunt resistor. It has high current passing through it and needs two sense lines to create a 4 point kelvin connection.
The high current and the assosciated sense lines are electrically the same net (e.g. VCC) but physically I want to route the sense line separate from the VCC power plane. So I want a net called for example VCC_SENSE. How do I connect these to my resistor without generating a DRC that two different nets are connected together?
can be done with a component with 2 copper pins on required layer. Pin may overlap in component. Create also a constraint region at the overlapping location. region should include both pad orign.
In brd, assign to this region a spacing constraint set with smd_pin to smd_pin set to -1
-1 value means "no check"
Thanks, this -1 means no check thing is a very useful tip.
