Detecting hotspots in physical design layout patterns utilizing hotspot detection model with data augmentation

A computer program product, the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by at least one computing device to cause the at least one computing device to perform steps of:

• receiving a given physical design layout pattern;
• utilizing a hotspot detection model to detect one or more potential hotspots in the given physical design layout pattern;
• performing a verification to determine whether a given potential hotspot of the one or more potential hotspots detected by the hotspot detection model comprises a real hotspot or a nonexistent hotspot;
• responsive to determining that the given potential hotspot comprises an actual hotspot, modifying the given physical design layout pattern to remove the actual hotspot;
• and
• responsive to determining that the given potential hotspot comprises a nonexistent hotspot, augmenting the hotspot detection model with additional training data generated based on the nonexistent hotspot;
• wherein augmenting the hotspot detection model with additional training data generated based on the nonexistent hotspot comprises:
• modifying one or more features in the given physical design layout pattern to generate one or more additional training layout patterns;
• and
• training the hotspot detection model with the one or more additional training layout patterns.

An apparatus comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured for:
• receiving a given physical design layout pattern;
• utilizing a hotspot detection model to detect one or more potential hotspots in the given physical design layout pattern;
• performing a verification to determine whether a given potential hotspot of the one or more potential hotspots detected by the hotspot detection model comprises a real hotspot or a nonexistent hotspot;
• responsive to determining that the given potential hotspot comprises an actual hotspot, modifying the given physical design layout pattern to remove the actual hotspot;
• and
• responsive to determining that the given potential hotspot comprises a nonexistent hotspot, augmenting the hotspot detection model with additional training data generated based on the nonexistent hotspot;
• wherein augmenting the hotspot detection model with additional training data generated based on the nonexistent hotspot comprises:
• modifying one or more features in the given physical design layout pattern to generate one or more additional training layout patterns;
• and
• training the hotspot detection model with the one or more additional training layout patterns.
