Multiple matrix switch: a high-performance universal switching system

The requirements and design considerations involved in the development of a "Smart" switching interface are described. The implementation of the Universal Pin concept is presented, along with a discussion of switch ing system performance and reliability. The relocation of certain functions such as syntax checks, pin validity checks, and path allocation and conflict checks, from their traditional location in the compiling system to self contained firmware contributes significantly to the flex ibility of the switching interface. The resulting simpli city with which the switching interface can be incor porated into various ATE system configurations is discussed.
