Abstract
The independent claims of this patent signify a concise description of embodiments. Roughly described, a design team prioritizes polygons of a circuit design layout. This information is then encoded into a layout database that is passed to the manufacturing team for correction further processing toward tape-out. The priorities may be used by an engineer to disposition errors found in the layout. For example, a failure may be waived. In another embodiment, the priorities are used during hotspot fixing, a process where failed features are corrected. In hotspot fixing, the priority can be used to make correction tradeoffs in favor of the highest priority features. Priorities are set during the correction to favor fidelity of the higher priority features over the lower priority features. Each embodiment reduces cost, and in some cases, improve final device performance. This Abstract is not intended to limit the scope of the claims.
