For the complex SoC and IP design one of the main constraints is area. The number of the logic cells in the design is the area and as we know that the area constraints Area constraints are limitations or restrictions placed on the physical size of the design during the ASIC design process. They define the maximum area that the design can occupy on the silicon die. These constraints are used to ensure that the final design fits within the available space and meets performance requirements. They are especially important in applications where space is limited, such as processing, computing. By considering all the above points the chapter is useful to understand the resource utilization, performance improvement by limiting the area, the clock mux logic, and the practical scenarios and use of the universal logic during the design.
