摘要： Some embodiments provide a configurable IC that includes a configurable routing fabric with storage elements. In some embodiments, the routing fabric provides a communication pathway that routes signals to and from source and destination components. The routing fabric of some embodiments provides the ability to selectively store the signals passing through the routing fabric within the storage elements of the routing fabric. In this manner, a source or destination component continually performs operations (e.g., computational or routing) irrespective of whether a previous signal from or to such a component is stored within the routing fabric. The source and destination components include configurable logic circuits, configurable interconnect circuits, and various other circuits that receive or distribute signals throughout the configurable IC.

摘要： Some embodiments provide a configurable integrated circuit (IC). The IC has configurable logic circuits for performing logical operations, configurable routing circuits for routing signals between the configurable logic circuits, and a network for monitoring data. In some embodiments a method uses at least a subset of the configurable logic circuits and a first subset of the configurable routing circuits to implement a user design circuit on the configurable IC. The method uses a second subset of the configurable routing circuits to pass signals to the network.

摘要： Some embodiments provide a configurable integrated circuit (IC) that has several configurable circuits and several user design state (UDS) circuits. The UDS circuits store user-design state values. The configurable IC also includes a debug network communicatively coupled to the UDS circuits. The debug network is for retrieving the user-design state values of several UDS circuits at various stoppages of the operation of the IC without retrieving configuration data that is used to configure the configurable circuits of the IC. The retrieved user-design state values at each stoppage are used as the checkpointed state of the IC while debugging the IC. In some embodiments, the debug network allows the checkpointing of only certain portions of the configurable IC.

摘要： Some embodiments of the invention provide configurable via programmable gate array (“VPGA”) with several configurable circuits arranged in a configurable circuit arrangement. In some embodiments, the configurable circuit arrangement is a configurable circuit arrangement that includes numerous (e.g., 50, 100, etc.) configurable circuits that are arranged in several rows and columns. This circuit arrangement also includes several direct offset connections, where each particular direct offset connection connects two configurable circuits that are neither in the same column nor in the same row in the circuit arrangement. In some embodiments, at least some direct offset connections connect pairs of circuits that are separated in the circuit arrangement by more than one row and at least one column, or by more than one column and at least one row. At least some of the configurable circuits are via programmable (“VP”) configured circuits.
