  • Patent number: 10324517
    Abstract: A FPGA-based system power estimation apparatus and a method for estimating the power of a target intellectual property (IP) circuit are provided. The system power estimation apparatus includes a FPGA and a power analysis circuit. The FPGA is configured to accommodate the target IP circuit. The power analysis circuit is disposed into the FPGA. The power analysis circuit retrieves an internal operation-state signal of the target IP circuit. The power analysis circuit examines the internal operation-state signal to determine an operation state of the target IP circuit and uses a power model to convert the operation state of the target IP circuit into at least one power value.
    Type: Grant

  • Patent number: 9773080
    Abstract: A thermal simulation device is applied to a transaction-level designed chip which includes a plurality of intellectual properties. The thermal simulation device includes a plurality of thermal-aware transaction-level power model circuits, a simulator, a translator and a thermal emulator. The thermal-aware transaction-level power model circuits corresponds to the respective intellectual properties, and are configured to a corresponding power information for each of the intellectual properties, and dynamically adjusts the power information according to temperature information. The simulator is configured to generate the corresponding temperature information of the intellectual properties according to compatible information. The translator is configured to generate the compatible information which is compatible with the simulator. The thermal emulator is configured to trigger the simulator and transmit the temperature information to the intellectual properties.

  • Patent number: 8051394
    Abstract: A yield evaluating apparatus and a method thereof are provided. The yield evaluating apparatus includes a spatial correlation module. The spatial correlation module receives at least one process-related data and a plurality of circuit layouts and obtains a correlation coefficient between unit elements in the circuit layouts according to the process-related data. The spatial correlation module calculates a spatial correlation between elements in each of the circuit layouts according to the correlation coefficient and selects one of the circuit layouts according to the spatial correlations.
