摘要： A clock signal is monitored to detect a transition from a first logic state to a second logic state. Once this transition is detected, subsequent transitions of the clock signal are ignored for a predetermined time period during which signal interference is most significant. After lapse of the predetermined time period, the clock signal is again monitored to detect subsequent state transitions. In some embodiments, the clock signal is delayed using a delay circuit to produce a delayed clock signal which is used to force the clock signal to the second logic state for a predetermined time period. In one embodiment, the predetermined time period is user-selectable via one or more selectable taps on the delay circuit.

摘要： A clock gating circuit is provided for a logic device that reduces device resource requirements, eliminates the need for users to define their own clock gating circuit, and eliminates undesirable clock signal disturbances, such as glitches and runt pulses. In one embodiment, the clock gating circuit includes an input terminal for receiving an input clock signal; an input terminal for receiving a clock enable signal; a storage latch coupled to receive the input clock signal and the clock enable signal, and in response, provide a clock gate control signal; and a logic gate coupled to receive the input clock signal and the clock gate control signal. The logic gate selectively routes the input clock signal in response to the clock gate control signal, thereby providing an output clock signal.

摘要： SEU-hardening series resistances loads are formed within the gate structures of cross-coupled inverters of a latch. For some embodiments, the gate contact for the input of each cross-coupled inverter has a sufficiently high resistance to provide the SEU-hardening series resistance. For other embodiments, a conductive trace layer coupled to the input of each cross-coupled inverter includes a high-resistivity portion that provides the SEU-hardening series resistance.

摘要： A method for using an FPGA to implement a crossbar switch is described. Rather than using signals routed through the general FPGA routing resources to control connectivity of the crossbar switch, the input signals only carry crossbar switch data, and the connectivity is controlled by FPGA configuration data. The crossbar switch is implemented in two parts: a template of basic and constant routing to carry input signals through the switch array in one dimension and output signals from the array in another dimension, and a connectivity part controlled by a connectivity table or algorithm to generate partial reconfiguration bitstreams that determine which of the input signals is to be connected to which of the output signals.
