Abstract: In a first mode, a control circuit generates a circuit design implementation with storage circuits in an integrated circuit by programming configuration memory bits via configuration resources. The storage circuits can be accessed for read and write operations during the execution of the circuit design implementation with the integrated circuit. In a second mode, the control circuit can perform read and write access operations at the storage circuits via configuration resources or via an interface circuit and interconnect resources that are allocated to the circuit design implementation. Typical applications for performing access operations at the storage circuits include fault injection and observation, statistical monitoring of the circuit design, initialization and the distribution of certain signals including reset signals, event sampling, just to name a few.

Abstract: An integrated circuit may include user storage circuits and scan storage circuits. The scan storage circuits may store data from the user storage circuits and provide the data to a user interface during a read-back operation. The user storage circuits may store data from the scan storage circuits, which the scan storage circuits may have received from the user interface during a write-back operation. The scan storage circuits may be arranged in a scan chain and controlled by a local control circuit. The integrated circuit may include multiple local control circuits that each control a sector of the integrated circuit. The local control circuits may communicate with a global control circuit over a communication network, and the global control circuit may communicate with the user interface.

Abstract: In server virtualization, the resources of an integrated circuit are partitioned into smaller portions, and each of these smaller portions is then operated independently. Software is used to represent the smaller portions as virtual environments. For the purpose of server virtualization, an integrated circuit may include several different circuit designs, each implemented in a secure partition in the integrated circuit. The operation of the circuit design implementations in the integrated circuit may require that each circuit design implementation can be verified as un-altered and from the respective user or owner and as having been approved by the integrated circuit owner and/or the circuit design implementation owner. The operation of the circuit design implementations in the integrated circuit may require that each circuit design implementation can be operated securely and independently of the other circuit design implementations in the integrated circuit.
