Given the importance of power, the Vivado tools support methods for obtaining an accurate estimate for power, as well as providing some power optimization capabilities. For additional information, see the Vivado Design Suite User Guide: Power Analysis and Optimization (UG907).
Recommended: When targeting UltraScale and AMD UltraScale+™
devices and using the Explore directives
or Explore-based strategies, you must manually enable block RAM power optimization by
running
power_opt_design or using opt_design -bram_power_opt after opt_design runs. AMD recommends
minimizing memory resources to reduce power. Review the bit utilization from the RAM
Utilization Report to find memory arrays with inefficient mapping. Also consider using
the HDL RAM_STYLE MIXED attribute for the most efficient mapping of arrays using a
combination of block memory and LUTRAMs.
