Abstract
Aspects disclosed in the detailed description include integrated circuit (IC) design methods using engineering change order (ECO) cell architectures. In particular, exemplary aspects provide a fill algorithm that is both single- and multi-row aware, considers a poly-pitch count, and utilizes metallization of the 'empty space' relative to a suite of available fill cells. The algorithm is also aware of timing critical logic elements and may place ECO fill cells in near proximity to such timing sensitive circuits or other margin critical circuits to allow for decoupling or, if there is a logic error, an ECO cell is placed such that the ECO cell is well positioned to be repurposed as a delay circuit or other function to aid in margin control. For maximum flexibility, the algorithm may also address both pre- and post-route applications.
