摘要： An integrated circuit is provided with diagnostic circuitry, such as serial scan chains or debug bus access circuits, with which communication is established using an interface circuit coupled with a bi-directional serial link to an external diagnostic device. The bi-directional serial link carries both data and control signals.

摘要： A method, system and unit for controlling the configuration of a transmission path coupling a first unit and a second unit is disclosed. The first unit and the second unit are configurable to support the transfer of information items over the transmission path in time-slots of successive transmission frames in accordance with a plurality of modes, each of the plurality of modes allocating differing numbers of time-slots within each frame to different types of information items. The method comprises the steps of: programming control logic of the first unit and the second unit with an indication of an ordered subset of the plurality of modes to be supported by the first unit and the second unit; configuring the first unit and the second unit to support the transfer the information items over the transmission path using a default one of the plurality of modes; and responsive to an indication requesting that a different mode be selected, causing the first unit and the second unit to be configured to support the next in the ordered subset of the plurality of modes indicated by the control logic. By providing within each unit a predetermined ordered list of modes to be supported by those units, it is only necessary to provide an indication that some change is required and the mode which needs to be changed to can be determined simply by referring to the ordered list. It will be appreciated that this provides a mechanism to switch efficiently between modes, significantly reduces the amount of data required to indicate the new mode and may improve the efficiency of total data transaction.
摘要翻译：公开了一种用于控制耦合第一单元和第二单元的传输路径的配置的方法，系统和单元。第一单元和第二单元可配置为根据多个模式支持在连续传输帧的时隙中的传输路径上的信息项的传送，多个模式中的每一个模式分配不同数量的时隙每帧到不同类型的信息项。该方法包括以下步骤：用第一单元和第二单元支持的多个模式的有序子集的指示来对第一单元和第二单元的控制逻辑进行编程; 配置第一单元和第二单元以支持使用多种模式中的默认模式通过传输路径传送信息项; 以及响应于请求选择不同模式的指示，使得所述第一单元和所述第二单元被配置为支持由所述控制逻辑指示的所述多个模式的有序子集中的下一个。通过在每个单元内提供要由这些单元支持的模式的预定的有序列表，仅需要提供需要进行某些改变的指示，并且可以简单地通过参考有序列表来确定需要改变的模式。应当理解，这提供了在模式之间有效切换的机制，显着地减少了指示新模式所需的数据量，并且可以提高总数据交易的效率。

摘要： A system and method for generating a testbench for a representation of a device to be incorporated in a data processing apparatus is provided. The representation of the device is configurable based on configuration data specifying predetermined attributes of one or more components of the data processing apparatus with which that device is to be coupled, and the testbench provides a test environment that represents those one or more components. The method comprises the steps of receiving the configuration data used to configure the representation of the device, and generating the testbench with reference to the configuration data and a first set of templates defining the test environment. By this approach, a matching testbench can automatically be generated for any particular instantiation of the configurable representation of the device to enable thorough verification testing of that instantiation of the device to be performed.
