  • Publication number: 20250285985
    Abstract: A digitally communicative circuit may use standardized interfaces for connection and communication with other circuit components. Such digitally communicative circuit may benefit from using wider variety of interconnect schemes with the respective interfaces for transmission and reception of data. Some chiplets may communicate using a high data bandwidth interface while other chiplets may communicate using interfaces with lower data bandwidth. Alternate interface is introduced that may facilitate scaled communication with Advanced Interface Bus 2.0 without translation circuitry and with different data bandwidth.

  • Patent number: 12294368
    Abstract: The present disclosure is directed to 3-D stacked architecture for Programmable Fabrics and Central Processing Units (CPUs). The 3-D stacked orientation enables reconfigurability of the fabric, and allows the fabric to function using coarse-grained and fine-grained acceleration for offloading CPU processing. Additionally, the programmable fabric may be able to function to interface with multiple other compute chiplet components in the 3-D stacked orientation. This enables multiple compute components to communicate without the need for offloading the data communications between the compute chiplets.

  • Patent number: 12273107
    Abstract: Embodiments of the present disclosure are related to dynamically adjusting a timing and/or power model for a programmable logic device. In particular, the present disclosure is directed to adjusting a timing and/or power model of the programmable logic device that operates at a voltage level that is not other than a predefined voltage defined by a voltage library. A system of the present disclosure may interpolate between voltage levels defined by the voltage libraries to generate a new voltage library for the programmable logic device. A timing and/or power model may be generated for the programmable logic device based on the new voltage library and the programmable logic device may be analyzed using the timing and/or power model at the interpolated voltage. The timing and/or power model may be used to generate a bitstream that is used to program the integrated circuit.

  • Patent number: 12266625
    Abstract: An integrated circuit includes a package substrate that includes first and second electrical traces. The integrated circuit includes first, second, third, and fourth configurable dies, which are mounted on the package substrate. The first and second configurable dies are arranged in a first row. The third and fourth configurable dies are arranged in a second row, which is approximately parallel to the first row. The first and third configurable dies are arranged in a first column. The second and fourth configurable dies are arranged in a second column, which is approximately parallel to the first column. The first electrical trace couples the first and third configurable dies, and the second electrical trace couples the second and third configurable dies. The second electrical trace is oblique with respect to the first electrical trace. The oblique trace improves the latency of signals transmitted between dies and thereby increases the circuit operating speed.

  • Patent number: 12216150
    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.
