Diffusion layer connecting is prohibited, how to write rules

[tech11]

Hi,

I'm one layout engineer and diffusion layer connecting is prohibited in my
design now, but since I modify my design based on last edition and need to
check out those diffusion used as connect. According to my experience, maybe
I may do it by soft-connect check, so I write such rules as below:

*INPUT-LAYER
........
CONNECT-LAYER = PSUB WEL ... CONM ...
*END

SELECT DIFF OVERLAP RSYMBOL DIFRES ;;RSYMBOL is one mask layer for diff
res;
AND DIFF PO1 DIFP1
AND DIFF PO2 DIFP2
NOT DIFF DIFRES DIFN1
NOT DIFN1 DIFP1 DIFN2
NOT DIFN2 DIFP2 DIFN3

AND DIFN3 CONT CONDF
SELECT ME1 OVERLAP CONDF CONM
AND CONM DIFN3 DIFCT

SCONNECT CONM DIFN3 BY DIFCT
SOFTCHK DIFN3 OUTPUT S_DIFN3 45

But I can't get the just part of diff, even I convert to calibre rule file
and run 'LVS SOFTCHK DIFN3 CONTACT' or 'LVS SOFTCHK DIFN3 UPPER MASK', How
should I do?

Thanks for your help

B.R.
