Forum Post: cdf parameter is changed when using generate all from source

Hi all, I have a schematic which consist of just one pcell. When I try to open layout of that pcell by using generate all from source feature in GXL , it should maintain the cdf parameters as in schematic. But it changes width of the cell. Width of the cell in schematic is 10u and when I use generate all from source to instantiate layout, the width changes to 9.9u in layout. I am using virtuoso 6.1.6 Please help to figure this out. Thanks Sanket
