OPTIMIZE_POWER_DURING_SYNTHESIS
Controls the power-driven compilation setting of Analysis & Synthesis. This option determines how
aggressively Analysis & Synthesis optimizes the design for power. If this option is set to 'Off', Analysis &
Synthesis does not perform any power optimizations. If this option is set to 'Normal compilation',
Analysis & Synthesis performs power optimizations as long as they are not expected to reduce design
performance. When this option is set to 'Extra effort', Analysis & Synthesis will perform additional power
optimizations which may reduce design performance.
