The data integrated into PDM with this designation is released after enough production silicon of a particular device family member has been characterized to provide full power correlation over numerous production lots. The characterization data for all blocks in the device fabric is included.
The accuracy of any power estimation is derived from the information input to the models. PDM uses the following models based on the device characterization:
- PREVIEW
- +/-30%
- ADVANCE
- +/-25%
- PRELIMINARY
- +/-20%
- PRODUCTION
- +/-15%
PDM and Report Power use the same models but Report Power has more details on the design being implemented such as resource settings and usage, net fanout, and net lengths which allows Report Power to give a more accurate estimation.
Note: For maximum process, the static power in a device should never exceed the reported
values in the tool.
