In this lesson, we will explore the concept of Register Transfer Level (RTL) logic and the importance of RTL power optimization. RTL design focuses on the functional behaviour of digital circuits, providing a bridge between high-level descriptions and gate-level implementations. We will walk through the process of synthesizing a multiplexer, demonstrating the transition from RTL code to a netlist. Then, we will also emphasize on the advantages of RTL power optimization, including early visibility of power consumption, efficient power-performance trade-off exploration, and faster analysis compared to gate-level power analysis. The insights gained from this lesson will help you understand the value of 'left-shift' methodology in the industry, prioritizing power optimization at the RTL stage.
