My design has an unrouted carry chain connection (COUT-->CIN slice pins) and when I examine the partially routed design (NCD) in FPGA Editor, I see that the slices are not aligned properly so that the dedicated carry chain routing resource is used. Why weren't the carry chain slices aligned properly? Shouldn't the router still be able to route the non-aligned carry connections?
