  • ATPG原理与实现——2.TetraMAX Flow

    TetraMAX Overview

     TetraMax Flow

    TetraMax的启动

    tmax [file]   如果要执行file直接跟file路径即可

    tmax -notcl(基本不用)  

    tmax -shell (不启动图形界面,一般用这个)(如果启动64位就加-64)

    1.读入library与netlist

    保存log文件

    BUILD-T> set_messages -log tmax.log -replace

    读入library和netlist

    BUILD-T> read_netlist mylibrary.v     (读verilog的library)

    BUILD-T> read_netlist my_asic.v    (支持以下格式:Verilog、EDIF、VHDL)

    2.Build ATPG Design Model

    build mode

    BUILD-T> run_build_model my_asic

    3.DRC

    DRC-T> run_drc DUT.spf

    (S rules)在shift mode下检查扫描链的工作顺序,并确保逻辑连接扫描输入到输出路径

    (C rules)检查连接到扫描触发器的clock和异步set/reset端口,以确保它们仅由主输入控制

    (C rules)从扫描capture mode切换到扫描shift mode并再次返回时,将检查clocks/set/resets的关闭状态

    (Z rules)检查多驱动程序网络是否存在争用

    4.setup and run ATPG

    TEST-T> run_atpg -auto   (推荐用auto,在覆盖率和pattern数之间提供最佳起点和折中点)

     5.保存ATPG pattern

    TEST-T> write_pattern mypat.stil -format stil

    Format

    Binary、STIL、WGL、WGL_flat、FTDL、TDL91、TSTL2

    Pattern Type Basic、Fast-Seq、Full-Seq
    Pattern Range First-Last
    Splitting patterns Multiple Files
    Compression Binary、GZIP

    6.参考脚本

    #save TetraMAX transcript to log file
    set_messages -log lab1.log -replace
    
    #Reading libraries and design
    read_netlist ../libs/ libs_tmax.v.gz
    read_netlist ../libs/rams.v
    read_netlist ../design_data/orca_final .v
    
    #set undefined modules as black boxes
    set_build -black_box PLL
    set_build -black_box CLKMUL
    
    #Run Build
    run_build_model
    
    # Perform scan Design Rules check
    run_drc ../ design_data/orca_final.spf
    
    #setup and run ATPG
    add_faults -a1l
    set_atpg -capture 4
    
    #Run ATPG engine 
    run_atpg -auto
    
    #Review Test Coverage
    report_summaries
    analyze_faults -class au
    report_patterns -summary
    
    #save Test Patterns
    write_patterns all_pats.stil   -foimat stil   -replace
    tetramax
