A Novel Approach To Dummy Fill For Analog Designs Using Calibre SmartFill

With small geometry silicon processes, additional nonfunctional geometric structures are required to maintain layer planarity during the chemical/mechanical polishing (CMP) phase of processing. The automated layout flows to generate such geometries tend to be designed primarily for large system on chip (SOC) digital designs. When applied to mixed-signal layouts, these flows have been seen to ha... » read more
