1 CPF
The Common Power Format is a standard promoted by the Low Power Coalition at Si2. CPF is also a TCL-based language that operates on speci?cation objects and the design objects. A design object is a module, instance, net, pin or port as they appear in the RTL.
The language can be used to express power design intent in terms of:
- Power domains : From physical, logical and analysis point of view
- Power logic : For example, level shifters and isolation logic
- Power mode : State mode table and transitions
2 UPF
The UPF speci?cation is in ASCII format that can be used to specify low power directives that encompass all aspects during the design ?ow. The power speci?cation provided in a UPF ?le can be used by simulation, synthesis, equivalence checking, physical design and physical veri?cation.
