有大佬给解释一下这两行drc的rule吗

yellti

1. ME1_Min_S_PERIMETER = DFM PROPERTY ME1_Min_S ME2_Min_S OVERLAP ABUT ALSO MULTI CONNECTED [ME1_Min_S_PERIMETER_LEN = PERIMETER(ME1_Min_S)]
   
2. ME1_Min_S_LEN_ERROR = DFM PROPERTY ME1_Min_ERROR ME1_Min_S_PERIMETER OVERLAP ABUT ALSO MULTI [ ME1_Min_LIT_LEN = ERROR_RATI0 * PERIMETER_RATIO * PROPERTY (ME1_Min_S_PERIMETER, "ME 1_Min_S_PERIMETER_LEN" )] [ERROR = LENGTH(ME1_Min_ERROR )- PROPERTY_REF(ME1_Min_LIT_LEN)] > 0

1. ME1_Min_S_PERIMETER = DFM PROPERTY ME1_Min_S ME2_Min_S OVERLAP ABUT ALSO MULTI CONNECTED [ME1_Min_S_PERIMETER_LEN = PERIMETER(ME1_Min_S)]

这一行的意思是ME1_Min_S 作为主层，主层之后的全部为副层；ME1_Min_S  ME2_Min_S 图形相交并且连接(需要连接是因为 CONNECTED 这一参数)，然后标记符合要求的ME1_Min_S的周长为ME1_Min_S_PERIMETER_LEN

1. ME1_Min_S_LEN_ERROR = DFM PROPERTY ME1_Min_ERROR ME1_Min_S_PERIMETER OVERLAP ABUT ALSO MULTI [ ME1_Min_LIT_LEN = ERROR_RATI0 * PERIMETER_RATIO * PROPERTY (ME1_Min_S_PERIMETER, "ME 1_Min_S_PERIMETER_LEN" )] [ERROR = LENGTH(ME1_Min_ERROR )- PROPERTY_REF(ME1_Min_LIT_LEN)] > 0
   

复制代码

这一行的意思是：找到ME1_Min_ERROR  ME1_Min_S_PERIMETER 图形相交的部分; PROPERTY 相当于指针，将指向上一步的ME1_Min_S_PERIMETER_LEN 的值，计算得出ME1_Min_LIT_LEN 的值；PROPERTY_REF是取ME1_Min_LIT_LEN的值，然后得出ERROR 的值，当ERROR >0时，ME1_Min_S_LEN_ERROR 输出，否则忽略。

另：ME1_Min_S_PERIMETER 和 ME1_Min_S_LEN_ERROR 输出的图形，都是各自主层的子集。
大概意思
