Patent number: 11803681Abstract: The embodiments herein rely on cross reticle wires (also referred to as cross die wires) to provide communication channels between programmable dies already formed on a wafer. Using cross reticle wires to facilitate x-die communication can be three to four orders of magnitude faster than using general purpose I/O. With a wafer containing cross reticle wires, various device geometries can be generated at dicing time by cutting across different reticle boundaries. This allows up to full wafer-size devices, or several smaller sub-wafer devices to be derived from one wafer. Although the programmable dies can contain defects, these defects can be identified and avoided when generating a bitstream for configuring programmable features in the programmable dies.Type: GrantFiled: March 22, 2021Date of Patent: October 31, 2023Assignee: XILINX, INC.Inventors: Zachary Blair, Alireza Kaviani

Patent number: 11784149Abstract: Embodiments herein describe a multiple die system that includes an interposer that connects a first die to a second die. Each die has a bump interface structure that is connected to the other structure using traces in the interposer. However, the bump interface structures may have different orientations relative to each other, or one of the interface structures defines fewer signals than the other. Directly connecting the corresponding signals defined by the structures to each other may be impossible to do in the interposer, or make the interposer too costly. Instead, the embodiments here simplify routing in the interposer by connecting the signals in the bump interface structures in a way that simplifies the routing but jumbles the signals. The jumbled signals can then be corrected using reordering circuitry in the dies (e.g., in the link layer and physical layer).Type: GrantFiled: April 20, 2021Date of Patent: October 10, 2023Assignee: XILINX, INC.Inventors: Ygal Arbel, Kenneth Ma, Balakrishna Jayadev, Sagheer Ahmad
