AR# 2772: FATAL_ERROR:basnc:basncsignal.c:262:1.61 mapping with -k switch
FATAL_ERROR:basnc:basncsignal.c:262:1.61 mapping with -k switch
FATAL_ERROR:basnc:basncsignal.c:262:1.61 - Could not find a bel for a signal on pin C1 of comp u0/u1/u1/modgen_0_ax_duplicate_name_0_CINt.
The error is dependent on use of the -k switch (map to 5-input functions)
For this particular case, map runs okay when the -k switch is not used. There are other known cases of this Fatal Error that are unrelated to the -k switch. If the error message mentions "pin C1" there is a good chance the the -k switch is involved.
