20090192765 | Techniques for Filtering Systematic Differences from Wafer Evaluation Parameters - A method, system and computer program product for filtering systematic differences from wafer evaluation parameters provides an efficient visual display and numerical map technique for observing wafer-level process variation. Measurement data is gathered from electronic circuits at multiple positions within multiple regions on one or more wafers and parameters are computed from the measurement data, which may be the measurement data values themselves. The set of parameters is filtered for expected systematic variation by computing a set of normalization values from the set of parameters and normalizing the data according to the normalization values. The normalized parameter set is then either presented in a visual display, e.g., by color mapping, or arranged in a numerical map of parameter value by location. | 07-30-2009 |
20130158953 | VISUALIZING SENSITIVITY INFORMATION IN INTEGRATED CIRCUIT DESIGN - A method, system, and computer program product for visualizing sensitivity information in integrated circuit (IC) design are provided in the illustrative embodiments. A plurality of sensitivity information corresponding to a first component in the IC design is received, wherein the plurality of sensitivity information includes a first sensitivity information indicating a first variation in a first electrical characteristic of a group of components as a result of a variation in an electrical characteristic of the first component. A plurality of aspects of the first sensitivity information are rendered in visual form to form a first visualization. The first visualization is presented on a schematic view of the IC design in an IC design tool such that the first sensitivity information is visually associated with the first component in the IC design. | 06-20-2013 |
20130159946 | GUIDING DESIGN ACTIONS FOR COMPLEX FAILURE MODES - A system, and computer program product for guiding design actions for complex failure modes in an integrated circuit (IC) design are provided in the illustrative embodiments. A probability of failure estimate of a circuit according to the IC design is received, the probability being determined using a simulation. A sensitivity of the probability of failure to a variable associated with a component in the circuit is calculated, wherein the sensitivity is determined by an estimation without the simulation. The sensitivity is depicted relative to the component in the IC design such that the sensitivity is associated with the component and a visual relationship between the component and the sensitivity is usable for adjusting a characteristic of the component to reduce the probability of failure of the circuit. | 06-20-2013 |

20140337357 | DOCUMENT TAGGING AND RETRIEVAL USING PER-SUBJECT DICTIONARIES INCLUDING SUBJECT-DETERMINING-POWER SCORES FOR ENTRIES - Techniques for managing big data include tagging of documents and subsequent retrieval using per-subject dictionaries having entries with subject-determining-power scores. The subject-determining-power scores provide an indication of the descriptive power of the term with respect to the subject of the dictionary containing the term. The same term may have entries in multiple dictionaries with different subject-determining-power scores in each of the dictionaries. A retrieval request for one or more documents containing search terms descriptive of the one or more documents can be processed identifying a set of candidate documents tagged with subjects and optional terms, and then applying subject-determining-power scores from the multiple dictionaries for the search term to determine a subject for the search term. The method then selects the one or more documents from the candidate documents according to the subject. | 11-13-2014 |
20150106376 | DOCUMENT TAGGING AND RETRIEVAL USING ENTITY SPECIFIERS - Techniques for managing big data include tagging of documents and subsequent retrieval using per-subject dictionaries having entries with some entries specially designated as entities. An entity indicates that the term in the entry has special meaning, e.g., brands (trademarks/service marks), trade names, geographic identifiers or other classes of terms. A dictionary may include a non-entity entry for a term and one or more entity entries, for different entity types. The entries may also include subject-determining-power scores. The subject-determining-power scores provide an indication of the descriptive power of the term with respect to the subject of the dictionary containing the term. The same term may have entries in multiple dictionaries with different subject-determining-power scores in each of the dictionaries. The entity distinctions for a term can then be used in tagging documents and processing retrieval requests. | 04-16-2015 |
20150134666 | DOCUMENT RETRIEVAL USING INTERNAL DICTIONARY-HIERARCHIES TO ADJUST PER-SUBJECT MATCH RESULTS - Techniques for managing big data include retrieval using per-subject dictionaries having multiple levels of sub-classification hierarchy within the subject. Entries may include subject-determining-power (SDP) scores that provide an indication of the descriptive power of the entry term with respect to the subject of the dictionary containing the term. The same term may have entries in multiple dictionaries with different SDP scores in each of the dictionaries. A retrieval request for one or more documents containing search terms descriptive of the one or more documents can be processed by identifying a set of candidate documents tagged with subjects, i.e., identifiers of per-subject dictionaries having entries corresponding to a search term, then using affinity values to adjust the aggregate score for the terms in the dictionaries. Documents are then selected for best match to the subject based on the adjusted scores. Alternatively, the adjustment may be performed after selecting the documents by re-ordering them according to adjusted scores. | 05-14-2015 |
