Abstract
Aspects of the disclosed technology relate to techniques of parasitic extraction using compact representation of process calibration data. Geometric information of a layout feature in the layout design comprising geometric parameters is extracted. Parasitic values associated with the layout feature are then computed based on the geometric information and one or more executable files selected in a plurality of executable files which are a compact representation of process calibration data.
Claims18
One or more non-transitory computer-readable media storing computer-executable instructions, the computer-executable instructions, when executed, causing one or more processors to perform a method, the method comprising:
- receiving a layout design;
- extracting geometric information of a layout feature in the layout design, the geometric information comprising geometric parameters of the layout feature;
- computing parasitic values associated with the layout feature based on the geometric information, the computing parasitic values comprising running one or more executable files selected in a plurality of executable files, the plurality of executable files being a compact representation of original process calibration data;
- and
- storing the parasitic values.
A method, executed by at least one processor of a computer, comprising:
- receiving a layout design;
- extracting, using the computer, geometric information of a layout feature in the layout design, the geometric information comprising geometric parameters of the layout feature;
- computing, using the computer, parasitic values associated with the layout feature based on the geometric information, the computing parasitic values comprising running one or more executable files selected in a plurality of executable files, the plurality of executable files being a compact representation of original process calibration data;
- and
- storing the parasitic values.
A system comprising:
- one or more processors, the one or more processors programmed to perform a method, the method comprising:
- receiving a layout design;
- extracting geometric information of a layout feature in the layout design, the geometric information comprising geometric parameters of the layout feature;
- computing parasitic values associated with the layout feature based on the geometric information, the computing parasitic values comprising running one or more executable files selected in a plurality of executable files, the plurality of executable files being a compact representation of original process calibration data;
- and
- storing the parasitic values.
