SIG_RENAME_RULESDQS$:DQS_P,CK$:CK_P,#$:_N,A10:A10_AP,A12:A12_BC_N

changes any pin ending in # to _N

adds P to any pin ending in CK (so CK->CK_P) 

adds P to any pin ending in DQS (so LDQS->LDQS_P) 

they can be identified as diff pairs

It also add AP suffix to A10 pin A10_AP

and the _BCN suffix to A12 pin (A12_BC_N)

(These suffixes did not appear in IBIS model)

we can also store this in a rename_rules.txt file and change

the entry to rename_rules.txt

if we do use the file, we need to add a backslash in front of the '#' character so that partBuilder does not think its a comment

rename_rules.txt would look like this:

DQS$:DQS_P

CK$:CK_P

\#$:_N

A10:A10_AP

A12:A12_BC_N
