1.4.1.3 Synthesize and Place and Route

In Libero, Synthesize has RAM optimization option. RAMs can be optimized for the following two modes.

  • High speed - RAM optimization is geared towards speed. The resulting synthesized design achieves better performance (higher speed) at the expense of more FPGA resources.
  • Low power - RAM optimization is geared towards low-power. RAMs are inferred and configured to ensure the lowest power consumption.

In Libero, the Place and Route has Power-driven option. Enable this option to run Power-Driven layout. The primary goal of Power-driven layout is to reduce dynamic power while maintaining timing constraints.

Important: For Normal demo design, in Synthesis option RAM is optimized for High speed, and in Place and route Power-driven option is disabled.
