Trying to use PrimeTime PX to do the power analysis

[kev7993]

Hi,

I am trying to use PrimeTime PX to do the power estimation.
However, I got some messages which I am not quite understand the meaning and I think these might effect the accuracy to the estimation.

Here is my flow:

1. setup the power model
set power_enable_analysis true
set power_analysis_mode averaged

2.
Link the library: .db file
Link the netlist: .v (which is generated after APR)

3.
read sdc file (I am not quite sure whether I have to read it or not?)
read spef file (generated from APR)
read saif file (generated from post-sim)

4.
check_power
report_power -verbose - hierarchy

When I check the report, I saw lots of the cells show "ZeroWireload" in the Wire_model column and "library default" shows Selection_type.
Does anyone know how to solve this problem?
or Is there any error in my flow?

Thanks,

hi,

give wireload models available ,i think you missed giving it.check for set_wireload_model constraint in sdc
