This standard defines a common interoperable format that will be used for the design of a) large-scale integration (LSI), b) packages for such LSI, and c) printed circuit boards on which the packaged LSI are interconnected. Collectively, such designs are referred to as” LSI-Package-Board” (LPB) designs. The format provides a common way to specify information/data about the project management, netlists, components, design rules, and geometries used in LPB designs.dition 1.0 2016-11 ？ IEEE Std 2401 INTERNATIONAL STANDARD Format for LSI-Package-Board interoperable design IEC 63055:2016-11(en) IEEE Std 2401-2015 THIS PUBLICATION IS COPYRIGHT PROTECTED Copyright ？ 2015 IEEE All rights reserved.
