2014.2 Vivado Power Anaysis - What impacts the results of the dynamic power estimation from report_power?
Description
What impacts the results of the dynamic power estimation from report_power?
Solution
The following will impact the results of the dynamic power estimation from report_power:
Implementation Models - The models are developed to balance simplicity and accuracy. Linear approximations are used to simplify the implementation.
Basic Modeling Fitting - The models are calibrated against a limited set of measured data points, and those datapoints are chosen to align to key data rates and operating modes.
Model Parameters - The models do not include all parameters, such as PRE/POST emphasis.
Adaptation - The models do not include adaptive logic, such as DFE and CTLE, which dynamically adjusts to match the system loss.
Process/Temperature - The process and temperature have little impact on the models
