A case has been seen where map incorrectly configures a CLB where a LUT drives the D inputs of both flops. One of the flop connections is dropped and the flop is left undriven.

Work around is to BLKNM the flops to different CLBs: INST "interface_cfg_out_reg<8>" BLKNM = "FOO" ; INST "interface_cfg_out_reg<9>" BLKNM = "BAR" ;
