1. A method of allowing relaxed design rules when implementing an integrated circuit design, comprising: defining a design for manufacturing (DFM) rule, the DFM rule corresponding to an alternate design rule from minimum design rule check (DRC) rules; defining a set of one or more of the DFM rules as a constraint group; associating the constraint group with an intelligent design parameterized cell master; applying the constraint group on an instance of the intelligent design parameterized cell master to an intelligent design cell to override a default DRC rule for the integrated circuit design; and performing layout of the integrated circuit design.
