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
