verify failed between address 0xXX and 0xXX

hi:

the problem I meet while run the NIOSII ESD 10.0 sp1.

verify failed between address 0xXX and 0xXX;

the address belongs to the sdram,I have check my project to make sure the dq[15..0] is bir-director and the connection is solid and so on...

the problem is still there.

So, I want to ask if the custom component of SOPC is the reason or not ?? I have add a SOPC component written of my own,but the quartusII project compiled successfully.

best regard
