| For a high speed application, we've had a request from engineering to create a special footprint for decouplers (0402, 0201) with a GND clearance under the pads. The clearances will be the same size as the pads, and will just affect the ground plane on layer 2. I'm trying to figure the best way to do this. I thought I could just build a special padstack, but Allegro (using XL 16.3) won't allow me to build an SMD padstack with an anti-pad unless I define a drill, bottom side pad, etc. But I'm not seeing a clean way to build this into the footprint symbol either. Any ideas? Thanks. Alexis Meehan Violin Memory Inc.
