    Fiducial Obstructs Round 2


      There was a previos post on Fiducial Obstructs, has there been any progress on this? I believe by using the Mechanical cell placement option for placing a fiducial, the fiducial designation within the tool gets lost and may not carry forward when generating the Placement files. Is there a way a user can modify the fiducials called in the Edit>Place>Fiducial menu? Similar to others, I'm looking to add a place obstruct and a route/plane obstruct. SMT vision systems need some copper clearances around fiducials. This would apply if you are flooding copper on exterior layers. Through the padstack editor the plane obstruct is greyed out and does not allow for any modification.

          Is this what you are trying to accomplish?


          These are screen shots from a Fiducial in my library. It clears planes and traces/vias around the fiducial.




          Add a custom pad to the fiducial padstack for the clearance needed. The custom pad is the obstruct.




          Good Luck,
