Logic synthesis is the process of converting high-level design descriptions, often written in hardware description languages like VHDL or Verilog, into a gate-level representation. This transformation allows designers to create digital circuits that can be implemented on hardware, such as FPGAs or ASICs. During logic synthesis, the design is optimized for various factors, including area, speed, and power consumption. The synthesized output consists of a network of logic gates that perform the desired functions, enabling engineers to create efficient and reliable electronic systems.
