Hi,
I am using PT PX to find difference in power values while feeding different inputs to a single-processor. The flow used --> VCD generation using modelsim --> PT PX power calculator.
The resulting power in both the cases is same and we are getting following warning in the log file while reading vcd file as,
---->>
read_vcd "base.vcd" -strip_path "/testb/resil_up/cpu"^M
Information: Checked out license 'PrimeTime-PX' (PT-019)
======================================================================
Summary:
Total number of nets = 26737
Number of annotated nets = 189 (0.71%)
Total number of leaf cells = 24142
Number of fully annotated leaf cells = 66 (0.27%)
======================================================================
Warning: VCD coverage on the design is too small. Power may be underestimated. (PWR-007)
---->>
I tried by making elongating the time duration of VCS generation to cover more design but no luck.
Has anyone faced similar problems and what is the recommended solution ?
Thanks & Best Regards
