Missing power in power compiler report on Encounter netlist.

deepu
deepu over 12 years ago
Hi folks,
  I am using SoCE for back end implementation and Syn power compiler for final power estimation. After reporting post layout power in power compiler, I noticed that out of the 2 blocks I have, 1 block (SPI) consumes 35% -power and another block(ECG_CQH) consumes less than 1% power. The report doesnt show where does the remaining power goes. ANy idea where is remaining power dissipated? Is it in the clock tree. PS this is final netlist with clock tree. Chk the attached image


Global Operating Voltage = 3    
Power-specific unit information :
    Voltage Units = 1V
    Capacitance Units = 1.000000pf
    Time Units = 1ns
    Dynamic Power Units = 1mW    (derived from V,C,T units)
    Leakage Power Units = 1pW
