I am assuming you are referring to adding traces within the etchback tool? (Manufacturing-->Etchback)Originally posted in cdnusers.org by BillAcito
The add trace is manual. Shorting schemes and design practices vary by such a great degree customer to customer, it would be very difficult to add automation to the trace add that would cover all of them (e.g. what rules should the tool use to determine the best location for the short? closest approach? most available space?)
Once placed, the tool does automate the creation of the mask openings, based on user defined spacing parameters.
