    • A system is provided for testing a first integrated circuit associated with at least a second integrated circuit in a semiconductor device, wherein at least some external terminals for the semiconductor device are to be shared by the first and second integrated circuits, and wherein the first integrated circuit is designed for normal operation and a test mode. The system includes a plurality of multiplexer circuits. Each multiplexer circuit is operable to receive a respective signal from the second integrated circuit when the first integrated circuit is in normal operation. Each multiplexer circuit is further operable to receive a respective signal from either the second integrated circuit or an associated external terminal when the first integrated circuit is in test mode. An external terminal of the semiconductor device operable to receive a signal for causing the first integrated circuit to transition between normal operation and the test mode.
    • 提供了一种用于测试与半导体器件中的至少第二集成电路相关联的第一集成电路的系统,其中用于半导体器件的至少一些外部端子将被第一和第二集成电路共享,并且其中第一集成 电路设计用于正常运行和测试模式。 该系统包括多个多路复用器电路。 当第一集成电路处于正常操作时,每个复用器电路可操作以接收来自第二集成电路的相应信号。 当第一集成电路处于测试模式时,每个多路复用器电路还可操作以从第二集成电路或相关联的外部端子接收相应的信号。 半导体器件的外部端子可操作以接收用于使第一集成电路在正常操作和测试模式之间转变的信号。
