I am trying to create a PCB using NI Ultiboard. My circuit is a SECPIC DC-DC converter and controlling the L1 current. This is my circuit:

schematic diagram

and I get this error:

Design rule error: Net "VOUT" close to net "3".
Design rule error: Net "3" close to net "VOUT".

large area of PCB

This is the area of the error (zoom of the second picture):

small area of PCB

I can't understand why I get this error, because in Multisim the circuit is working fine. Can anyone explain the cause for the error?

You've got a hole there with a copper ring around it: The blue ring.

It is actually too close to the next pin.

  • \$\begingroup\$ remove the copper ring. (your question strikes me as a bit of strange, what did you expect?) \$\endgroup\$ Apr 30, 2019 at 16:47
  • \$\begingroup\$ the thing is that I cant remove this copper ring , and tell you the truth I cant undestand why there is copper ring there in the first place , I have other SMD components and they dont have copper rings . Why do I have this rings ? and I am new to the PCB thing so I am sorry if I ask base questions \$\endgroup\$ Apr 30, 2019 at 17:12
  • \$\begingroup\$ you're the one who (accidentally) added the copper ring. I'm sorry, removing elements from your schematic is something you should be able by now. \$\endgroup\$ Apr 30, 2019 at 17:59
  • \$\begingroup\$ I deleted the ring but for some reason it appears every time ... \$\endgroup\$ Apr 30, 2019 at 18:10
