Various embodiments are directed at methods and systems for implementing automatic fixing of a layout, implementing fuzzy pattern replacement, and implementing pattern capturing in a layout of an electronic circuit design. Various processes or modules comprise the act or module of identifying a first pattern from within an electronic circuit layout. The processes or modules also comprise identifying a fixing process or a replacement pattern for the first pattern and the act of performing pattern replacement or pattern fixing on the first pattern. The processes or modules may further comprise the act or module of searching the layout for patterns that match the first pattern, and the act or module of performing pattern replacement of pattern fixing on the patterns that match the first pattern. Some embodiments are also directed at articles of manufacture embodying a sequence of instructions for implementing the processes described here.
