  • Method and apparatus for improving multiplexer implementation on integrated circuits
    Patent number: 7506278
    Abstract: Systems, methods, software, and techniques implementing a multiplexer mapper tool can be used to construct a binary decision diagram (BDD) or related structure representing a series of dependent multiplexers. Once in this form, the BDD can be manipulated in a variety of ways including reordering of nodes according to multiplexer selector and minimizing the BDD using conventional techniques. Once properly processed, the BDD can be further separated into smaller BDDs and mapped to existing cell library design elements.
