  • Publication number: 20230129176
    Abstract: A method includes mapping an aging measurement circuit (AMC) into the core fabric of an FPGA and operating the AMC for a select time period. During the select period of time, the AMC counts transition of a signal propagating through the AMC. Timing information based on the counted transitions is stored in a timing model in a memory. The timing information represents an aging characteristic of the core fabric at a time that the AMC is operated. An EDA toolchain uses the timing information in the timing model to generate a timing guard-band for the configurable IC die. The AMC is removed from the core fabric and another circuit device is mapped and fitted into the core fabric using the generated timing guard-band models. The circuit device is operated in the configurable IC die based on the timing guard-band models.

  • Patent number: 11610856
    Abstract: An integrated circuit package may be formed comprising an interposer with a center die and a plurality of identical integrated circuit dice positioned around the center die and attached to the interposer, wherein the center die is the switch/router for the plurality of identical integrated circuit dice. The interposer comprises a substrate, a central pattern of bond pads formed in or on the substrate for attaching the center die, and substantially identical satellite patterns formed in or on the substrate for attaching identical integrated circuit dice. The central pattern of bond pads has repeating sets of a specific geometric pattern and wherein the identical satellite patterns of bond pads are positioned to form the same geometric pattern as the specific geometric pattern of the central pattern of bond pads. Thus, substantially identical conductive routes may be formed between the center die and each of the identical integrated circuit dice.
