Integrated circuit with interface tile for coupling to a stacked-die second integrated circuit
First Claim
1. An integrated circuit die comprising an array of tiles, the tiles arranged in rows and columns, wherein one of the tiles is a routing tile having four edges, the routing tile having other tiles adjacent each of its four edges, the routing tile comprising:
- a first routing conductor that extends to a first of the four edges of the tile; and
a micropad that has an exposed and conductive upper surface, the micropad being couplable to the first routing conductor such that a signal received onto the micropad from a source external to the integrated circuit die can be communicated from the micropad to the first routing conductor and to the first of the four edges of the tile;
wherein the first routing conductor is a conductor segment that extends to the first edge of the tile, andwherein the first edge of the tile abuts a second tile, the second tile having a conductor segment that meets the first routing conductor end-to-end at the first edge to form a conductor that extends from a point inside the tile to a point inside the second tile.

Abstract
A general purpose interface tile of a first integrated circuit includes a plurality of micropads. A second integrated circuit may be stacked on the first integrated circuit such that signals from the second integrated circuit are communicated through the micropads and the interface tile to other circuitry on the first integrated circuit. Similarly, signals from the first integrated circuit are communicated through the interface tile and the micropads to the second integrated circuit. In the event that the first integrated circuit is a programmable logic device having a programmable interconnect structure, the interface tile is part of and hooks into the programmable interconnect structure and provides a general purpose mechanism for coupling signals from the second integrated circuit to the programmable interconnect structure and/or for coupling signals from the programmable interconnect structure to the second integrated circuit.
