Dear cris72,

please tell me how to know the address range of master.

address width is 8 bit;

data width is 16 bit;

i mean

32-bit data =>16-bit data => 32 bit data. in middle i am reducing data width to 16 bits again converting to 32 bit. here another warning is "no [byteenable] signal is asserted so master will writes into slave SPURIOUSLY. 


CDMA_ENCODING(MASTER):CDMA_DECODING(slave) address (0x0..0x1f)  is out of range of masters address (0x0..0xf).

what will be the address range.kindly tell me sir.

its showing that CDMA_ENCODING (master) address range is 0x0..0xf

CDMA_DECODING(slave) range is 0x0..0x1f.(it assigned automatically)..ITS CAUSING ERROR, I AM ATTACHING MY ADDRESS MAP IMAGE.. KINDLY LOOK IT AND SUGESST ME YOUR SOLUTION WHERE TO CHANGE MY ADDRESS RANGE.AND SPECIFY THAT ADDRESS RANGE SIR.PLEASE.
