Top level port :
ss_n : BUFFER STD_LOGIC_VECTOR(0 DOWNTO 0);
constraint file ucf :
NET "ss_n" LOC = "AC24" ;# | S=true; #keep={yes|no|true|false}| keep=true
Error :
ERROR:ConstraintSystem:59 - Constraint <NET "ss_n" LOC = "AC24" ;>
[dfg.ucf(18)]: NET "ss_n" not found. Please verify that:
1. The specified design element actually exists in the original design.
2. The specified object is spelled correctly in the constraint source file.
I tried change type of port from "BUFFER" to normal "OUT" like
and use buffer :
but not helped me , then i found solved link and use KEEP and S attributes also not help why ? http://www.xilinx.com/support/answers/34258.html
also not helped me, very strange problem

I tried change type of port from "BUFFER" to normal "OUT" like
Code:
ss_n : OUT STD_LOGIC_VECTOR(0 DOWNTO 0);
Code:
--OBUF_CamOE : OBUF
-- generic map ( DRIVE => 12, IOSTANDARD => "DEFAULT", SLEW => "FAST")
-- port map ( O => ss_n(0), I => ss_n_i(0) );but not helped me , then i found solved link and use KEEP and S attributes also not help why ? http://www.xilinx.com/support/answers/34258.html
