Abstract:
A method and apparatus for inserting antenna diodes into an integrated circuit design is described. During the design process, diode cells are placed in filler cells of the integrated circuit design, but left unconnected. Subsequently, when an ECO is received requiring antenna diodes to be inserted in the integrated circuit design, only metal mask changes are required to connect the diode cells to gate electrodes of specified transistors or cells. Since the diode cells are already part of the original integrated circuit design layout, it is not necessary to perform a re-layout of the design cells with the diode cells performing antenna diode functions, thereby speeding up the EDA redesign process as well.
