Honored ContributorHI! thepancake,
the design above is only a submodule for display , so I want to use LogicLock to constraint my every module. I have read the document you suggested before, however, the question is still exist,the design needs 1196 LEs , So I set the Width to 15, Hight to 12 , (15*12*10=1800>1196),the Origin is X2_Y2, and I'm so sure that there will be no errors , but when I compile the design,the error message is: Error: Fitter requires that more entities of type logic cell be placed in a region than are available in the region. Error: Region "lower-left" corner: X2_Y2; Region "upper-right" corner: X16_Y13 Error: Region can accept 1380 entities of type logic cell, but the Fitter needs to place 2220 of them in this region Fortunately, when I set the Width to 25, Hight to 12(25*12*10=3000),the Origin is X2_Y2,the compilation is OK,. I wonder when I set the Width to 15, Hight to 12(15*12*10=1800>1196),the Origin is X2_Y2, Region only can accept 1380 entities of type logic cell ! why ? In addition,I can't understand why the Fitter needs to place 2220 of them in this region correctly, I need your help!
