In many areas of the semiconductor industry, System-on Chip (SoC) power analysis and management is a critical process for maintaining low-power profiles. Due to the complexity of modern SoC designs and the definition of their power management strategies, it iscommon to reuse available resources such as Intellectual Properties (IP) and power intent descriptions in the Unified Power Format (UPF). However, this is typically initiated at the Register Transfer Level (RTL) and beyond. In this study, we provide a new, earlier approach to enable system-level power intent definition and power management strategy description around IPs or entire SoCs. This approach follows UPFsemantics and allows for the creation of reusable, power-aware IP models. In addition, it adds a description of clock intent into this modeland simplifies the separation of designs into clock domains and the application of dynamic power reduction techniques. The approach is builtaround the PwClkARCH power modeling and estimation tool and its capabilities are demonstrated using an example of reusing power-awareSystemC-TLM IP models from NXP’s i.MX8 SoC series.
