Abstract:
United Power Format (UPF) is used in a design to specify the power intent of the design. The UPF file is used at all the stages in the verification starting from RTL verification to GLS to place & route stages however it is often the case that UPF needs to be modified at next verification stage. For example UPF at RTL level needs to be modified to be used at GLS level due to design-hierarchy changes, cell placements and cell connections. This creates problem of managing different UPFs at various stages, checking their equivalence to make sure the consistency. In this paper we want to highlight all the differences between an RTL UPF and a GLS UPF. We would also propose a methodology to write RTL UPF in such a way that minimal changes are required during gate level power verification.
