    How to Add Specially Created Via Padstacks to Just the Design Database vs. Library? Reply
    For a design, trying to keep some specially created via padstacks out of the general library path and instead just keep with the design database.  In the Allegro Constraint Manager, there are two options for assigning vias to the nets but it's not clear how to get these new, specially-created via padstacks to only appear using the ‘Show vias from the database' and NOT the ‘Show vias from the library'.  Any ideas or information is greatly appreciated; perhaps it's something simple being overlooked.

     One technique is add a series of paths such as...

    ./Padstacks

    ../Padstacks

    <Library Home>/Padstacks

    There is a subtle reason for the multiple paths but it should be obvious why it would good to add a local project Padstacks folder.  You can override the master library this way.  Likewise for symbols.

    Other things you can is build a "Blind/Buried" via and just rename the through-hole via to something new.  The CM will pick up the name.
