1253                 with m.If(~wb_in.stall & ~stbs_done):
1254 #               -- That was the last word ? We are done sending.

actually annoyingly you will need a 2nd temporary variable at line 1247
stbs_zero and test that at line 1253 

comb stbs_zero.eq(stbs==0)
comb stbs_fone.eq(stbs_done)

          with m.If(~wb_in.stall & ~stbs_zero):

otherwise a comb loop is created on stbs_done.
