Layout jumper

archive
archive over 17 years ago

Hi All,
 
I have design a single side PCB on Allegro 15.7. Some times it was necessary to implement a SMD Jumper for jumping over other signals. I have place this jumpers on the schematic (design entry CIS) and connected bode pins of the jumper to the same signal.
It works, but I have a small cosmetic problem, for each jumper I placed, I get on the Layout guide (open connection).
Does some one know if there is a possibility to design a library symbol with two pins that can be automatically connected to the same potential?
 
Thanks in advance
 
Gustavo

    Yes, this can be done. Select the part > right click > Edit Part > select the pin and change it's type to 'Power' - a power type pin is (automatically) connected to the net where in the net name is same as the (power) pin name.

    Use a zero ohm resistor

    Thanks for the responses,

    A zero ohm resistor has the same problem; each end of the component will be connected to a different net. So that it is not possible to connect both pins to the same net as example GND or so on.

    I will try to define the pins as power pins.

    I had tried to change the pin type to power pin. For the schematic it is clear, but on the layout I always get a ratsnet on between both pins. The result is the same as using a zero ohm resistor.

    That is a snapshot of the layout, were you can see the ratsnets. The PCB is functional routed by 100%. The big risk is the possibility to overlook really open connections.
