2.4.5. Intel® Quartus® Prime Compiler Settings

The Intel® Quartus® Prime software provides settings that optimize power for the full design.

To set the optimization mode on the Intel® Quartus® Prime software, click Assignments > Settings > Compiler Settings.

Figure 11. Compiler Settings for Power Optimization

The two power optimization modes direct the Compiler to prioritize one optimization metric.

Power (High effort—increases runtime)

High effort modes enable additional optimizations that increase compilation time and do not affect design performance. High Power Effort mode guides the Compiler to spend additional compilation time reducing routing utilization, which saves dynamic power.

Power (Aggressive—increases runtime, reduces performance)

Aggressive modes increase compilation time and make trade-offs that may harm other optimization metrics (performance, area, etc.). In Aggressive Power mode, the Compiler attempts to reduce the routing usage of signals with the highest specified (via Signal Activity File) or estimated toggle rates, saving additional dynamic power but potentially affecting performance.
