Abstract: Methods and systems to manage an environmental condition, such as power consumption and/or temperature, of an integrated circuit (IC) device by controlling a bandwidth of a packet-based communication interface of the IC device (e.g., a PCIe interface). Bandwidth may be controlled by controlling delay between packets or controlling delay of a handshake signal. Delay may be increased when the environmental condition reaches a first threshold. Delay may be reduced when the environmental condition falls to a second threshold. Bandwidth may be regulated with proportional-integral control provided by a firmware controller and/or hardware. Bandwidth may be separately controlled for upstream and downstream paths based on bandwidth utilization of the respective paths. Bandwidth control may utilize codes stored in selectable registers. The IC device may include a field programmable gate array (FPGA) and may be configured as an accelerator card.

Abstract: Using a flat shell for an accelerator card includes reading a flat shell from one or more computer readable storage media using computer hardware, wherein the flat shell is a synthesized, unplaced, and unrouted top-level circuit design specifying platform circuitry. A kernel specifying user circuitry is synthesized using the computer hardware. The kernel is obtained from the one or more computer readable storage media. The synthesized kernel is linked, using the computer hardware, to the flat shell forming a unified circuit design. The unified circuit design is placed and routed, using the computer hardware, to generate a placed and routed circuit design specifying the platform circuitry and the user circuitry for implementation in an integrated circuit.
