ERROR:LIT:407 - CI of CARRY4 symbol "<inst>" must be driven by another CARRY4 compone
Hello
I am using ISE 12.3 to simulate my design,the device family is virtex 6.I got this error while mapping my design - ERROR:LIT:407 - CI of CARRY4 symbol "<inst>" must be driven by another CARRY4 component.
When i looked for it in Xilinx i got a link - **broken link removed** where this error and its solution is given.
I am using Linux(Fedora - 11) as my platform.As mentioned in the solution i tried to set the environment using setenv XIL_MAP_OLD_SAVE 1 command in the root command prompt.After that i used echo $XIL_MAP_OLD_SAVE to check the result.The env was set.I restarted ise, but still when i am trying to map my design i am getting the same error.
Is there any other way to get rid of this error.
Any advice will be of great help.
Thanks in advance.
