新手版图问题求助~

各位eetop的大神，小弟刚毕业从事IC设计，版图遇到各种问题，求解。
工艺库用的是IBM bicoms .18的工艺，跑DRC遇到下面问题不知道怎么解决。
1,(RX P+Junction to RX NW Contact) within NW for no latchup <= 53.0 um.
2,PC that intersects RX must have a PC area <= 320.00 sq.um.
3,V1 must be within MT >= 0.00 um.
4,Gates (not over TG) (NOT covered by GRLOGIC) OR Gates (under QT MIM capacitor)must have a RX tiedown by M1 metal.

如果版图布局有好意见的也麻烦各位大神指导一下~

版图布局

找你身边的同事debug吧，别人也只是猜一下，毕竟没有你们的design rule文件，看着费劲啊

你的layout 上面 gardring 太少了吧，所以drc 会报 关于latch up的错。

1,(RX P+Junction to RX NW Contact) within NW for no latchup <= 53.0 um.
PICKUP 離太遠BODY cont 離太遠
2,PC that intersects RX must have a PC area <= 320.00 sq.um.
PC 面積 太大
3,V1 must be within MT >= 0.00 um.
V1 需要有 MT
4,Gates (not over TG) (NOT covered by GRLOGIC) OR Gates (under QT MIM capacitor)must
have a RX tiedown by M1 metal
可能是 Gates 沒連到 M1
沒有 design rule 只能憑經驗猜一猜

谢谢哦
