5.0 PPR - Possible cause of 'Error 5805: Constraints to mapping symbol conflict'

ソリューション




PROBLEM: The following error can occur in cases where the F function
generator of a CLB is dis-allowed in a .cst file, but the H
function generator is used and hand placed in the design.

*** PPR: ERROR 5805:
Constraints assigned to mapping symbol '$1I1442/$1I246
(type=HMAP, output signal=$1I1442/COD)(netlist LOC(s)=CLB_R8C3.H,
cstfile
LOC(s)=!CLB_R8C3.F+!CLB_R9C3.F+!CLB_R10C3.F+!CLB_R11C3.F+!CLB_R12C3
.F+!CLB_R13C3.F+!CLB_R14C3.F) are in conflict.



WORKAROUND: There is no workaround other than removing the offending
constraint.
