4.1 Pin-muxed集成 受限于IO资源,Pin-muxed的集成不能支持所有CLUSTER同时进行测试,IO复用我们设置3个reuse group,其中将8个CLUSTER的intest,分两次进行测试,reuse group如下表所示: Pin-muxed的集成示意图如下图所示(受限于篇幅,图中没有画出XSTile): 图32 众核香山处理器的Pin-muxed集成 4.2 SSN集成 南湖微架...
Rules for Detecting Faults • Rules of the Game: Tester access to the DUT is only allowed through its primary I/O ports because Internal Probing of IC Too Costly! Way of Chips to be Tested The internals of the...
Analog/IP DFT比较常用的架构有Internal/External Loopback, JTAG program test,IO pin test muxing, embedded reg/mem sampling 等等。这部分重点是需要和 Analog/IP designer 紧密合作,共同确定后续lab和量产测试的spec;还有就是因为包含了Analog部分,如何完成仿真验证需要特别注意。
IJTAG网络(Internal JTAG)设计范例通过IJTAG网络对MBIST、EDT、OCC以及其他DFT的静态信号进行控制。IJTAG电路是基于IEEE1687协议进行设计的控制电路,最终挂载在JTAG TAP下,由SIB、TDR两部分电路构成,如下图所示: 图4 整芯片IJTAG网络DFT的新增端口设计范例规定了DFT新增端口的类型,以方便与外部模块通信,新增端口如下表...
