unconnected pin on bel BEL_core_i/Rawm_0[1].G:D of comp core_i/Rawm_0[1]. Its

The problem in 1_5is2 is an optimization routine that moves a flipflop from G to F
location when the input is fed by COUT of another slice. This optimization routine
does not clean up the slice content correctly when the flop involved is a FDRS
type flop.

Solution

This error is fixed in version 2.1i.
