11/26/2020, 8:33 PMThat looks fairly large, that's going to interrupt your PDN right ?
Also with metal density rules, wouldnt a lot of the area get re-filled ?

11/26/2020, 8:34 PMMm, I might be misreading the scale actually. This sqaure is the whole user area ?

11/27/2020, 11:43 AMJust small hint, It's often OK to put a logo only on the top metal layer. Logos on lower layers only make sense when doing (SEM) inspection during production or if one plans to decapsulate the chip. GIven the WLCSP planned I am not even sure if logo on top metal will be visible.
