CR-8000 Design Force Fanout

Tech Tip: Fanout using CR-8000 Design Force Dragon EX

CR-8000’s Design Force Dragon EX tool can be used to fanout BGAs. Simply draw a Dragon area around your BGA. Then select the Dragon area and create a strategy to fanout the pads of your BGA. You can create steps to fanous pads based on signal names. The ground pins can be fanned out to the ground plane layer using a specified via. You can control the layers used, fanout direction, and vias.

Pin pairs of nets other than power/ground nets can be created using a macro command. Pin pairs are needed in the Constraint Browser to obtain values such as “measured route length” and “Manhattan ratio.”
