Library Exchange Format
Library Exchange Format (LEF) is a specification for representing the physical layout of an integrated circuit in an ASCII format. It includes design rules and abstract information about the cells. LEF only has the basic information required at that level to serve the purpose of the concerned CAD tool. It helps in saving valuable resources by providing only an abstract view and thus consuming less memory overhead. LEF is used in conjunction with Design Exchange Format (DEF) to represent the complete physical layout of an integrated circuit while it is being designed.
