Abstract:
1. A computer-aided design (CAD) system configured for correcting a circuit design layout containing a process critical feature, comprising: a processor; a memory connected to the processor; and a non-transitory computer usable medium having instructions embedded therein, the instructions configured to cause the processor to perform the operations of: evaluating a detected error in the circuit design layout; said evaluating comprising: the instructions further configured to cause the processor to perform the operations of: creating a metric for process criticality based on a predicted edge movement and a resulting deviation in an electrical performance characteristic derived from the detected error; selecting a layout geometry based on the metric to determine whether the layout geometry requires modification to improve an electrical performance characteristic; and automatically performing a modification to the geometry layout to improve the electrical performance characteristic.
