IBIS File Types and Structures
Advanced package models can be either placed inside the .ibs file itself or in a package
file (.pkg).
• Electrical board description files, *.ebd
An electrical board description file (.ebd file) is defined to describe the connections of a
board level component between the board pins and its components on the board.
The IBIS files contain the same basic information and can be thought of as having three main
sections:
• Header section—contains information about the IBIS version, the file name, and the
process or organization responsible for the information.
• Component section—describes the component name, pinout, pin to buffer mapping, and
package electrical characteristics.
• Model section—describes the behavior of each unique buffer used in a component.
An IBIS .ibs file consists of:
• File Header Section
• [Component]
• [Model]
• [Define Package Model]
• [End]
A package .pkg file consists of:
• File Header Section
• [Define Package Model]
• [End]
