    How to setup DRC to allow packages overlap?

    I am doing a very compact design, and some packages have to be layout overlap. But the DRC continully tells me an error(I know it will be OK). So my question is how to setup DRC for overlap packages?BTW, I am using 16.5

    Many thanks

    Orcad or Allegro? 

    Allegro has flexible Design-For-Assembly DRC settings.

    But, Orcad only checks collisions between a polygon on the DFA layers.

    I always suspected I could suppress/hide the error marker and move forward.  B-)
