  • Patent number: 11309894
    Abstract: A programmable integrated circuit (“PIC”) device includes configurable logic blocks (“LBs”), routing connections, and configuration memory for performing user defined programmed logic functions. Each configurable LB, in one example, includes a set of lookup tables (“LUTs”) and associated registers. The LUTs, for example, are configured to generate one or more output signals in accordance with a set of input signals. The registers are arranged so that each register corresponds to one LUT. In one embodiment, a group of registers, instead of assigning to a group of LUTs across multiple configurable LBs, is allocated or configured as embedded signature registers in PSD. For example, a first register which corresponds or physically situated in the vicinity of first LUT can be designated as an embedded signature register for storing a fixed value or signature information for facilitating device or IC identification.

  • Patent number: 11216022
    Abstract: A field-programmable gate array (“FPGA”) contains a configurable semiconductor organized in multiple clock regions with a clock fabric for facilitating user-defined logic functions. The clock fabric provides a set of regional clock signals (“RCSs”) generated from a clock source with a high clock signal quality (“CSQ”) for clocking logic blocks in a clock region. Also, a set of neighboring clock signals (“NCSs”) or inter-regional clock signals are generated from a neighboring clock source(s) for clocking logic blocks in two neighboring regions. In addition, the clock fabric is operable to provide secondary clock signals (“SCSs”) generated from the RCSs with a low CSQ for clocking logic blocks with less time-sensitive logic operations.

  • Patent number: 11095294
    Abstract: A phase-locked loop (PLL) and a method for calibrating a VCO therein are provided. The PLL comprises a frequency-phase detector, a charge pump, a loop filter, a VCO, a divider and a calibration circuit. The calibration circuit is used to acquire a frequency of an output signal of the VCO, to calibrate the frequency of the output signal according to an expected frequency, and to acquire frequency control parameters of the VCO at the current signal frequency. The amplitude and gain of the output signal are kept constant according to the amplitude control parameters and gain control parameters. The PLL can meet the demands on frequencies of multiple protocols and can adaptively look up and stabilize the suitable frequency. It solves the issue that the amplitude of the output signal of the VCO is not constant when the PLL operates in a large frequency range.
