Placing feature cells is similar to placing normal cells, except that feature cells have a parameter set table associated with them. These let you select from a list of preset dimensions prior to placing the cell. Where a dimension is left blank in the parameter table, you can specify it at the time of placing the cell. As well, after placing the feature cell, you can apply a different parameter set to it. In the following example, you will work with the feature cell created in the previous section.
