  • Publication number: 20250217357
    Abstract: An instruction query method, a computer program product, and an associated query system are provided. A software program is stored in the computer program product, and the software program performs the instruction query method. The instruction query method includes the following steps. Firstly, a language translator translates a non-English query string into an English query string according to a language identification code. Then, a prompt tuning module transforms the English query string into an English interactive prompt string according to at least one high-relevance token vector. The at least one high-relevance token vector relates to the operating instructions of an electronic device. Afterward, the language translator translates an English reply string into a non-English reply string according to the language identification code. The English reply string is generated based on inferences made from the English interactive prompt string.

  • Patent number: 8099705
    Abstract: Embodiments of a device (such as a computer system or a circuit tester), a method, and a computer-program product (i.e., software) for use with the device are described. These systems and processes may be used to statistically characterize interdependencies between sub-circuits in an integrated circuit (which are referred to as ‘aggressor-victim relationships’). In particular, statistical relationships between the aggressors and victims are determined from values of a performance metric (such as clock speed) when the integrated circuit fails for a group of state-change difference vectors. Using these statistical relationships, a worst-case sub-group of the state-change difference vectors, such as the worst-case sub-group, is selected. This sub-group can be used to accurately test the integrated circuit.
