摘要： In accordance with an embodiment of the invention, precision control of error injection may be accomplished by way of synchronous error signals accompanying data transfers along various pipeline stages of a data path. The synchronous error signals may be used to trigger error events in a given protocol logic block (i.e. in a given sub-component of the data path). The protocol logic block is configurable to determine whether any action is to be taken upon the assertion of the error signal. Multiple error events may be triggered as the data signal (and its accompanying synchronous error signal) passes through pipelined functions of the data path so as to create complex error conditions. In addition, deterministic handling of created errors may be accomplished using a loopback path with bypassable blocks on both forward and reverse transformations. Other embodiments, aspects and features are also disclosed.
摘要翻译：根据本发明的实施例，错误注入的精确控制可以通过伴随数据路径的各个流水线级数据传输的同步误差信号来实现。同步误差信号可用于触发给定协议逻辑块（即在数据路径的给定子组件中）的错误事件。协议逻辑块是可配置的，以确定是否在断言错误信号时采取任何动作。随着数据信号（及其伴随的同步误差信号）通过数据路径的流水线功能，可能会触发多个错误事件，从而创建复杂的错误条件。此外，可以使用在正向和反向转换两者上具有可旁路块的环回路径来实现所创建的错误的确定性处理。还公开了其它实施例，方面和特征。

摘要： The present application discloses apparatus and methods for increasing channel utilization for a high-speed serial interface of an integrated circuit (IC). A new circuit architecture is disclosed which provides circuitry that may be programmed flexibly to support a multitude of different channel bonding schemes. In accordance with one aspect of the invention, the new architecture decouples the granularity of control-signal channel bonding from the granularity of data-aggregation channel bonding. This advantageously allows optimization of configurations for both types of channel bonding. In another aspect of the invention, the logical boundaries of bonded user channels are decoupled from the physical boundaries of the PCS modules. This decoupling advantageously eliminates a rigid constraint of previous architectures.

摘要： Systems and methods are provided for avoiding memory address conflicts in systems containing shared memory. Upon system power up, programmable logic device integrated circuits, microprocessors, and other integrated circuits with processing capabilities are provided with unique initialization data memory addresses. Each unique initialization data memory address corresponds to a respective non-overlapping block of memory in the shared memory. During initialization operations, the integrated circuits retrieve initialization data from the shared memory using the unique initialization data memory addresses. The integrated circuits can be organized using a master-slave architecture. The master can load the initialization data memory addresses into the slave integrated circuits using communications circuitry that is active after the slaves have powered up but before the slaves have been initialized.

摘要： A reconfigurable device loads I/O configuration information from a diagnostic interface during testing. The device includes a configurable I/O connection for communicating values with other devices. A diagnostic interface communicates the value of the I/O connection to a tester. A diagnostic controller in the device has a first mode for communicating the value on the I/O connection to the tester via the diagnostic interface, and a second mode for receiving an I/O configuration attribute value for the I/O connection from the diagnostic interface thereby modifying the configuration of the I/O connection. The device also includes a configuration controller that retrieves device configuration information from a configuration device in response to a signal. The signal can originate from an external source or from the diagnostic controller in response to a configuration instruction received via the diagnostic interface. The diagnostic interface may be a JTAG interface.
