Systems and methods are provided for adjusting gain of a receiver. Adaptation circuitry is operable to identify, based on a matrix representation of a receivers output generated from horizontal and vertical sweeps of the receivers output, an eye opening of the receivers output. The adaptation circuitry is also operable to determine whether a size of the eye opening needs to be changed. When it is determined that the size of the eye opening needs to be changed, the adaptation circuitry is operable to generate a digital signal to change a gain setting of the receiver. When the signal at the receivers output is under-equalized, the AC gain of the receiver is increased. When the signal at the receivers output is over-equalized, the AC gain of the receiver is decreased.

Systems and methods for interface block. The interface block includes input/output modules distributed along the interface block and a mid-stack module interspersed within the input/output modules. The input/output modules include at least one data module and at least one command module. At least one of the input/output modules is shared by an adjacent pair of channels. Each of the input/output modules is configured to interface with a memory device via a silicon interposer or equivalent. The mid-stack module is in communication with the input/output modules via programmable logic circuitry. The mid-stack module may include independent clock quadrants. Each clock quadrant is configured to operate at different phases where each phase is aligned to a respective core clock.

Various structures and methods are disclosed related to routing and programming circuitry on integrated circuits (IC) that have arrays of programmable resistive switches. In some embodiments, routing structures utilize densely populated resistive switch arrays to provide for efficient selection circuits that route into and out of logic regions. In other embodiments, programming circuitry is provided to help maintain relatively consistent programming current throughout an array of resistive switches to be programmed. In other embodiments, methods are provided for programming resistive switches without violating given power constraints. These and other embodiments are described further herein.

A method of monitoring operations of a set of ICs. The method loads a first set of configuration data into a first IC for configuring a group of configurable circuits of the first IC to perform operations of a user design. The method receives a definition of an event based on values of a set of signals in the user design and a set of corresponding actions to take when the event occurs. The set of signals includes at least one signal received from a second IC. The method generates an incremental second set of configuration data based on the definition of the event and the set of corresponding actions. While the first IC is performing the operations of the user design, the method loads the incremental second set of configuration data into the first IC and monitors the signals received from the second IC at the first IC.
