All About Physical Design

Physical design is the process of converting a logical description of an electronic system into a physical layout that can be fabricated. This involves designing the layout of the system’s components, including transistors, interconnects, and power sources, while taking into account factors such as timing, power consumption, and physical constraints.

The physical design process typically involves several stages, including floorplanning, placement, routing, and verification. During floorplanning, the designer defines the overall size and shape of the chip and partitions it into functional blocks. Placement involves determining the optimal location of each block within the chip while taking into account factors such as power and signal integrity. Routing involves connecting the blocks together using a network of interconnects while ensuring that the timing and power requirements of the design are met.

Verification is an important part of the physical design process, as it involves ensuring that the physical layout of the chip matches the original design specifications and that it functions correctly. This involves running a variety of simulations and tests to check for issues such as timing violations, signal integrity problems, and power consumption.
