Description
Power intent definition is a core part of modern low-power digital design. IEEE 1801 UPF provides a standardized specification method for describing supply connectivity, power domains, power switching behavior, retention requirements, isolation rules, and simulator semantics without hardcoding those assumptions into RTL. This separation keeps functional logic clean while giving verification and implementation tools a precise model of how the design behaves across different power modes. The technical flow starts from the supply interface. Supply ports define where power and ground enter the design hierarchy, while supply nets describe how those resources are distributed internally. Explicit supply net connections remove ambiguity between external power sources and internal power structures. Supply sets then group related power and ground nets into reusable supply contexts, making it possible to define valid power states and reason consistently about domain activity. Power domains organize the design into regions that share the same power behavior. Each domain can be associated with specific supply sets, controlled independently, and analyzed under different operating states. Switc...
