  •  Here is the top of my current LEF file:

    VERSION 5.6 ;
    NAMESCASESENSITIVE ON ;
    BUSBITCHARS "[" ;
    DIVIDERCHAR "/"  ;

    UNITS
        DATABASE MICRONS 1000  ;
    END UNITS

    MANUFACTURINGGRID 0.005 ;
    USEMINSPACING PIN OFF ;
    USEMINSPACING OBS OFF ;

    PROPERTYDEFINITIONS
        PIN ASSIGNTYPE STRING ;
    END PROPERTYDEFINITIONS

    Do you see any major differences between this and your lef? Can you cut and paste the part of your log file where it complains about reading in the LEF?
