ELF: Executable and Linkable Format A program header table, if present, tells the system how to create a process www.doorway.ru used to build a pro-cess image (execute a program) must have a program header table; relocatable files do not need www.doorway.ru Size: KB. A Library Exchange Format (LEF) file contains library information for a class of designs. Library data includes layer, via, placement site type, and macro cell definitions. The LEF file is an ASCII representation using the syntax conventions described in "Typographic and Syntax Conventions". Manual LEF License Key.

LEF, DEF LIB. The LEF file is the abstract view of cells. It only gives the idea about PR boundary, pin position and metal layer information of a cell. To get the complete information about the cell, DEF (Design Exchange Format) file is required. In this 3 sections are defined, i.e. technology, site, macros.

An executable file using the ELF file format consists of an ELF header, followed by a program header table or a section header table, or both. The ELF header is always at offset zero of the file.
