  • Publication number: 20200186149
    Abstract: A programmable device may have logic circuitry formed in a top die and memory and specialized processing blocks formed in a bottom die, where the top die is stacked directly on top of the bottom die in a face-to-face configuration. The logic circuitry may include logic sectors, logic array blocks, logic elements, and other types of logic regions. The memory blocks may include large banks of multiport memory for storing data. The specialized processing blocks may include multipliers, adders, and other arithmetic components. The logic circuitry may access the memory and specialized processing blocks via an address encoded scheme. Configured in this way, the maximum operating frequency of the programmable device can be optimized such that critical paths will no longer need to traverse any unused memory and specialized processing blocks.

  • Publication number: 20190227590
    Abstract: A circuit system includes an interposer that has a first clock network and first and second integrated circuit dies that are mounted on the interposer. The first integrated circuit die includes a phase detector circuit, an adjustable delay circuit that generates a second clock signal in response to a first clock signal received from the first clock network, and a second clock network that generates a third clock signal in response to the second clock signal. The second integrated circuit die comprises a third clock network that generates a fourth clock signal in response to the first clock signal received from the first clock network. The phase detector circuit controls a delay provided by the adjustable delay circuit to the second clock signal based on a phase comparison between phases of the third and fourth clock signals.

  • Publication number: 20190146028
    Abstract: A method includes mapping an 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.

  • Publication number: 20190131268
    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.
