Abstract: Methods and systems for configuring a programmable logic device include receiving configuration data at an input of a first sector of the programmable logic device and dynamically routing the configuration data through the first sector to a second sector of the programmable device by selecting a first routing path out of the first sector or a second routing path out of the first sector.

Abstract: Integrated circuits may include memory interface circuitry that communicates with memory. The memory interface circuitry may include latch circuitry that receives a data strobe enable signal from the memory controller and latches the data strobe enable signal using a data strobe signal received from the memory. The integrated circuit may include logic circuitry that gates the data strobe signal using the latched data strobe enable signal. The logic circuitry may pass the data strobe signal in response to activation of the latched data strobe enable signal. The integrated circuit may include counter circuitry that monitors the gated data strobe signal. The counter circuitry may monitor the gated data strobe signal by counting pulses in the gated data strobe signal to produce a counter value. When the counter value reaches a target value, the logic circuitry may block the data strobe signal from passing to the memory controller.

Abstract: An integrated circuit may include a delay circuit that receives an input signal at a first logic level and produces a delayed output signal at a second logic level at an output terminal. The integrated circuit may include a preset circuit coupled to the delay circuit. The preset circuit may receive the input signal and pre-drive the delayed output signal to an intermediate logic level that lies between the first and second logic levels.
