Techniques for determining and using static regions in an inverse design process

A product line comprising a plurality of physical devices;

• wherein a physical device of the plurality of physical devices includes a design region, wherein the design region connects one or more input ports and one or more output ports;
• wherein the design region of the physical device includes a static design area and a customized design area;
• wherein structures within the static design area for the physical device are specified by a segmented design determined by an inverse design process, and wherein the segmented design for the structures within the static design area is the same for the physical device of the plurality of physical devices;
• and
• wherein structures within the customized design area for the physical device are specified by a segmented design determined by an inverse design process.

A non-transitory computer-readable medium having logic stored thereon that, in response to execution by one or more processors of a computing system, causes the computing system to perform actions comprising:

• conducting an inverse design process to generate a plurality of segmented designs corresponding to a plurality of device specifications, wherein each segmented design includes a design region comprising structures optimized based on a corresponding device specification during the inverse design process;
• determining at least one highly impactful design area based on the plurality of segmented designs, wherein the at least one highly impactful design area is a subarea of the design region, and wherein the determining includes:
• analyzing field magnitudes in corresponding regions of the plurality of segmented designs;
• and
• selecting at least one region wherein an average field magnitude is greater than average field magnitudes in other regions;
• and
• designating the at least one highly impactful design area as a static design area.
