    • An Automated Test Equipment (ATE) system is configured to test a Device Under Test (DUT). The ATE system stores a Procedure Description Language program. The ATE system interprets the program, thereby causing a configured scan path to be set up in the DUT and causing bit values to be loaded into that scan path. During testing, it is sometimes desirable to change only bit values in certain scan path bit locations. In a data recirculation operation, the ATE system shifts bit values, on a bit-by-bit basis, out of the configured scan path via the TDO terminal of the DUT and shifts back in either the shifted out bit value or a replacement bit value. The shift back into the configured scan path occurs via the TDI terminal of the DUT so that each bit value in the scan path is replaced with its previous value or a replacement value.
    • 自动测试设备(ATE)系统被配置为测试被测器件(DUT)。 ATE系统存储过程描述语言程序。 ATE系统解释程序,从而导致在DUT中设置配置的扫描路径,并将位值加载到该扫描路径中。 在测试期间,有时期望仅改变某些扫描路径位位置中的位值。 在数据再循环操作中,ATE系统通过DUT的TDO端将位值逐位移出配置的扫描路径,并以移出的位值或替换位值返回 。 通过DUT的TDI端子进入配置的扫描路径,使得扫描路径中的每个位值被替换为其先前的值或替换值。

    • A system and method for sharing a communications link between multiple protocols is described that comprises a system comprising a communications interface configured to exchange information with other systems using at least one of a plurality of protocols; a protocol select register (1108) that stores a value that selects a protocol from among the plurality of protocols to become an active protocol; and a state machine accessible to the communications interface, the state machine used to control the exchange of information through the communications interface according to the active protocol. The active protocol is used by the communications interface to exchange information while the remaining protocols of the plurality of protocols remain inactive. The state machine sequences through a series of states that cause the communications interface to operate according to the active protocol, and that are designated as inert sequences under the remaining protocols.
    • 描述了用于共享多个协议之间的通信链路的系统和方法,其包括:系统,其包括被配置为使用多个协议中的至少一个与其他系统交换信息的通信接口; 协议选择寄存器(1108),其存储从所述多个协议之中选择协议以成为有效协议的值; 以及通信接口可访问的状态机,用于根据活动协议通过通信接口来控制信息交换的状态机。 通信接口使用活动协议来交换信息,而多个协议的剩余协议保持不活动。 状态机通过使通信接口根据活动协议进行操作的一系列状态进行排序,并在其余协议下被指定为惰性序列。
