7.1i SP4 BitGen - Bitstream does not contain block RAM routing frames in Module-based Partial Reconfiguration

説明

General Description: 

Module-based Partial Reconfiguration fails if configuration frames for the reconfigurable module contain block RAM routing frames (regardless of whether or not block RAM are used).

ソリューション

To work around this issue, add a block RAM range constraint to the Reconfiguration Module in the UCF file (as in the example below): 

 

 #Start of Area Group Constraints 

INST "reco_module" AREA_GROUP = "AG_reco_module" ; 

AREA_GROUP "AG_reco_module" MODE=RECONFIG ; 

AREA_GROUP "AG_reco_module" RANGE = SLICE_X0Y159:SLICE_X53Y0 ; 

AREA_GROUP "AG_reco_module" RANGE = RAMB16_X0Y19:RAMB16_X4Y1 ; 

 

This issue will be resolved in 8.1i SP1.
