Patent ID: 7882453

Claim:
A method of forming a pool of die designs for use in manufacturing dies, comprising: receiving a pool of die designs, each of the die designs specifying a metal programmable base layer; selecting a die design for use in fabrication of a die if a die design in the pool of die designs provides a desired functionality; selecting a die design for customization and use in fabrication of a die, customizing the metal programmable base layer specified by the die design, and adding the customized die design to the pool of die designs if a die design in the pool of die designs provides the desired functionality after the die design is customized; and forming a custom die design for use in fabrication of a die and adding the custom die design to the pool of die designs if no die design in the pool of die designs provides the desired functionality or the desired functionality after the die design is customized, the custom die design specifying a metal programmable base layer, the custom die design providing the desired functionality; wherein the pool of die designs includes multitile die designs; wherein the multi-tile die designs include selectable components for metallization in an I/O slot of the die design for providing inter-tile intra-die communication.
