I used the netlist synthesis by DC and the same library in Firtst Encounter.
Without any change(IPO or CTS), I get a very different power estimation report.
From DC the power report is :
Cell Internal Power = 23.9280 mW (84%)
Net Switching Power = 4.4078 mW (16%)
---------
Total Dynamic Power = 28.3358 mW (100%)
on the other hand, from First Encounter
average power(default): 1.1235e+02 mw
average switching power(default): 2.5025e+01 mw
average internal power(default): 8.7247e+01 mw
average leakage power(default): 7.7970e-02 mw
both use the statistic toggle rate 20%
I have thought about the reason from WLM, but when I use the SPEF extracted from the FE to backanotate to the DC(PC) with read_parasitic -elmore *.spef
I get the same report from DC.
I am very confused now, can I share your experience~~
