Hello,



I made an Entity with an Process using Xilinx 7.1 .



Then made:



GEN_A : GenInt port Map ( clk_prg_i => clk_prg_i , res_i => res, high_o => high_Gen, low_o => low_Gen);


In UCF-File:



inst "GEN_A" AREA_GROUP=Group_A; AREA_GROUP "Group_A" RANGE=SLICE_X3Y1:SLICE_X33Y33;


and became the following error:



NgdBuild:753 - Line 41 in 'LFSR_CS_Test.ucf': Could not find instance(s) GEN_A' in the design. To suppress this error specify the correct instance name or remove the constraint.



I need Help with this Error.



Thanks



Peer

Is this your top entity? If not, you have to use the full path, i think this is called "traversing hierarchy" in XST manual. Also, this instance may be optimized away from the design during synthesis

Have a look at the floorplanner for the right names.
