求助一下各位大佬，关于带ISO的pick up ring和guarding的画法

pormisingzz

Every ISO5, ISO20, ISO40, ISO60, ISO80, ISO100 and ISO120 block region must have a BNP N+AA pick up ring,
and this ISO mark layer every edge must interact with 1st P-substrate P+AA guard ring(from internal to outside) and mustn’t be a ring
器件是smic下的nde60_hs_iso_ckt，本人对pick up ring了解不深，不清楚BNP N+AA pick up ring具体怎么画，只是打了两层guardring，先p再n，但没有解决问题，向各位大佬求助一下，感谢指导
