Synthesis transforms design specs into hardware from "summary" of System Design by Andreas Gerstlauer,Rainer Dömer,Junyu Peng,Daniel D. Gajski
Synthesis is a crucial step in system design where high-level design specifications are translated into hardware. In this process, the abstract system description is transformed into a concrete hardware implementation. The goal of synthesis is to generate a hardware description that meets the specified functional and performance requirements. During synthesis, the design specifications are refined and mapped onto hardware components such as logic gates, flip-flops, and memory elements. The synthesis tool analyzes the design specifications to determine the optimal hardware architecture that satisfies the given constraints. This involves a series of transformations that convert the high-level design into a register transfer level (RTL) description. One of the key tasks in synthesis is logic synthesis, where the control and data paths of the design are synthesized into a network of logic gates. This involves optimizing the logic structure to improve performance, area, and power consumption. Another important aspect of synthesis is technology mapping, where the logical gates are mapped onto specific physical components available in the target technology. After synthesis, the hardware description is further refined through a process known as optimization. This involves applying various techniques to improve the quality of the design in terms of area, performance, and power consumption. The optimized hardware description is then ready for the next stage in the design flow, such as simulation, verification, and implementation. In summary, synthesis plays a critical role in the system design process by transforming high-level design specifications into a hardware description. This process involves refining the design specifications, mapping them onto hardware components, and optimizing the hardware description to meet the specified requirements. Through synthesis, designers can efficiently translate their design ideas into hardware implementations that can be realized in silicon.
