Abstract
Aspects of the invention relate to techniques for detecting and correcting electrical hotspots in a layout design for a circuit design comprising an analog circuit. Layout parameters for device instances associated with electrical constraints are first extracted. Based on the extracted layout parameters, electrical parameter variations for the device instances may be computed to identify one or more electrical hotspots in the layout design. A sensitivity analysis of the one or more electrical hotspots is performed to generate repair hints. Based on the repair hints, the layout design is adjusted.
