Abstract
An apparatus, a method, a method of manufacturing an apparatus, and a method of constructing an integrated circuit are provided. The apparatus includes a memory; and a processor configured to acquire K values with N peaks, where K and N are integers; select J of the N peaks and include the J peaks in track, where J is an integer less than or equal to N; determine a metric using acquisition non-coherent summations (NCSs) and track NCSs of coherent correlations; determine to not abandon the measurement based on the metric; and form a measurement responsive to determining to not abandon.
Claims20
An apparatus, comprising:
- a memory;
- and
- a processor configured to:
- acquire K values with N peaks, where K and N are integers;
- select J of the N peaks and include the J peaks in track, where J is an integer less than or equal to N;
- determine a metric using acquisition non-coherent summations (NCSs) and track NCSs of coherent correlations;
- determine to not abandon the measurement based on the metric;
- and
- form a measurement responsive to determining to not abandon.
A method, comprising:
- acquiring, by a processor, K values with N peaks, where K and N are integers;
- selecting J of the N peaks and including the J peaks in track, where J is an integer less than or equal to N;
- determining a metric using acquisition non-coherent summations (NCSs) and track NCSs of coherent correlations;
- determining to not abandon the measurement based on the metric;
- and
- forming a measurement responsive to determining to not abandon.
A method of manufacturing an apparatus, comprising:
- forming the apparatus on a wafer or a package with at least one other apparatus, wherein the apparatus comprises a memory and a processor configured to acquire K values with N peaks, where K and N are integers, select J of the N peaks and include the J peaks in track, where J is an integer less than or equal to N, determine a metric using acquisition and track non-coherent summations (NCSs) of coherent correlations;
- determine to not abandon the measurement based on the metric;
- and form a measurement responsive to determining to not abandon;
- and
- testing the apparatus, wherein testing the apparatus comprises testing the apparatus using one or more electrical to optical converters, one or more optical splitters that split an optical signal into two or more optical signals, and one or more optical to electrical converters.
A method of constructing an integrated circuit, the method comprising:
- generating a mask layout for a set of features for a layer of the integrated circuit, wherein the mask layout includes standard cell library macros for one or more circuit features that include an apparatus comprising a memory and a processor configured to acquire K values with N peaks, where K and N are integers, select J of the N peaks and include the J peaks in track, where J is an integer less than or equal to N, determine a metric using acquisition and track non-coherent summations (NCSs) of coherent correlations;
- determine to not abandon the measurement based on the metric;
- and form a measurement responsive to determining to not abandon;
- disregarding relative positions of the macros for compliance to layout design rules during the generation of the mask layout;
- checking the relative positions of the macros for compliance to layout design rules after generating the mask layout;
- upon detection of noncompliance with the layout design rules by any of the macros, modifying the mask layout by modifying each of the noncompliant macros to comply with the layout design rules;
- generating a mask according to the modified mask layout with the set of features for the layer of the integrated circuit;
- and
- manufacturing the integrated circuit layer according to the mask.
