  • Logic Bist Arch

    一般现在多用的都是offline BIST的架构,可以分为4大类:

    1)those assume no special structure to the circuit under test;

    2)those that make use of scan chains in the circuit under test;

    3)those that configure scan chains for test pattern generation and output reponse analysis;

    4)those that use the concurrent checking circuitry of the design;

    BIST Archi for circuit without scan design

    需要增加的逻辑:two LFSR,two multiplexers,(CSBL arch)

    1)第一个multiplexer选择PI或PRPG的输入;

    2)CUT是一个或combinational或sequential的circuit;

    3)第二个multiplexer选择PO或SISR的输出;

    4)SISR比较最终的signature与嵌入的golden signature的区别;

    STUMPS架构:

    CBILBO架构:

    BIST arch for circuit with scan chain

    LSSD On-Chip Self-Test

    CUT中的scan design的output移动到SISR中,并将pass/fail的error signal给Sout.

    BIST Arch Using Concurrent Checking Circuit

    Concurrent Self-Verification(CSV)

    CBILBO是唯一一种可以使用pesudo-exhausting的架构;

    CSV是唯一一种不需要额外的SISR或MISR的架构;

    STUMPS目前应用最广的架构;但是是使用pseudo-random pattern generation的架构;
