Unique Power Modeling Technology：

PhyBolt employs an innovative power modeling approach that significantly enhances simulation efficiency and accuracy. By reading library files (.lib) under multiple temperature (T) and voltage (V) conditions, the tool abstracts intermediate power calculation results into a highly efficient mathematical model. This model allows rapid substitution of arbitrary voltage, temperature, and frequency (V/T/F) parameters, enabling instantaneous power evaluation under diverse operating conditions. Compared to full simulations, this method improves computational speed by two orders of magnitude. Additionally, PhyBolt supports the construction of activity mode-specific power models based on multiple toggle information files, ensuring comprehensive coverage of diverse operational scenarios. This capability allows designers to accurately simulate power consumption across various working modes without repetitive full-scale analyses.
