LUP.1 { @ Any N+ OD injector or an N+ OD injector cluster connected to an I/O pad must be surrounded by a P+ guard-ring.
@ Any P+ OD injector or a P+ OD injector cluster connected to an I/O pad must be surrounded by a N+ guard-ring.
LUP.2 { @ Within 15 um space from the OD injector connected to an I/O pad, a P+ guard-ring is required to surround an NMOS or an NMOS cluster. And an N+ guard-ring is required to surround a PMOS or a PMOS cluster.
LUP.3.1.1 { @ If all of guard-ring width >= 0.2 um (e.g. width of guard-ring of LUP.1) >= 2
LUP.5.1.2 { @ If one of guard-ring width < 0.2 um (e.g. width of guard-ring of LUP.1 and LUP.2) >= 3
都是数字部分(IIC)直接与IOpad相接的mos报的错,整个数字部分(IIC)外面打了N+和P+保护环,但还是有错,也不可能在数字部分里面打保护环(自动生成的),怎么解决这个问题呢,大神求助谢谢!!
