  • Patent number: 11620423
    Abstract: Systems and methods are described herein for attribute-point-based timing formal verification of application specific integrated circuit (ASIC) and system on chip (SoC) designs. A target circuit design having a first set of netlists and timing constraints is received. A plurality of key clock-pin-net-load-setting attributes are extracted from the first ported netlists and timing constraints. The clock-pin-net-load-setting attribute mismatch in the result report is checked between the target circuit design and a golden circuit design by comparing the plurality of target attributes with a plurality of golden attributes of the golden circuit design after the target design database is loaded for static timing analysis (STA).

  • Patent number: 11537911
    Abstract: Techniques for nurturing content creation are provided. In one technique, a particular user is identified. Candidate entities are identified based on one or more attributes of the particular user. For each candidate entity, a feedback sensitivity measure of content creation of the candidate entity is determined. The feedback sensitivity measure is generated based on an amount of feedback, from other users, to content that the candidate entity has created. A score is then generated for the candidate entity based on the measure. A ranking of the candidate entities is determined based on the score of each candidate entity. A subset of the candidate entities is selected based on the ranking. The subset of the candidate entities is transmitted over a computer network to be presented on a computing device of the particular user.

  • Publication number: 20220330472
    Abstract: A degradable aroma product with seeds wrapped therein includes plant seeds and growth carriers coated or mixed with plant nutrients and aromatizers. The degradable aroma product may be in the form of an aroma card with the growth carriers being made of paper pulp, or alternatively, in the form of an aroma sachet with the plant seeds and the growth carriers or the aroma card wrapped in a degradable packaging bag. When the degradable aroma product has been used over a period of time and no longer produces fragrance, it can be directly buried in soil without forming any pollutant and accordingly, meets the requirement of plastic and waste reduction. Further, with the plant nutrients, the plant seeds can grow into trees, flowers or fruits more easily to enable sustainable development of healthy circle of life (i.e. the product design concept of cradle-to-cradle), carbon reduction and environmental protection.
