sram bist scripts

主要三个script:

mbist_run: call mbistarchitect tool

run.do:run bist flow  bist setup => bist mode(bist gen / bist insert) =>bist integrate

mbist.do: config bist logic fsm (定义算法 定义修复逻辑 定义output )

mbist_run:

mbistarchitect   ../netlist/top_name.v     -rep   -top top_module_name   -logfile   bist_log      -insertion -dofile  ../scripts/run.do -lverilog  ../models/instance_name.v

run.do:

//1.setup mode(perform load library and load design object and arg configurate)

///1.1 load lib

load library ../models/instance.lib

///1.2 configuration

add clocks 0 clock

add new port bist_mode -dir in

add new port  bist_done  -dir out

add new port bist_fail -dir out

add pin sharing bist_clk clk

report clocks

report pin sharing

//2. bist mode (perform add new controller or add existing controller)

set system mode bist

report memory instances

add new controller u_top_bist -do ../scripts/mbist.do u_instance_name

report memory instances

add pin mapping bist_mode u_top_bist/test_h

add pin mapping bist_done u_top_bist/test_done

report pin mapping

//3. insert bist logic(perform the generation activity and the insertion activity)

insert bist logic

report controllers

save design -rep -inc rtl

//4.integration mode(perform add pattern translation and delet patterns)

set system mode int

add pattern translation -all

//5.about pattern

integrate pattern

report pattern translation

report controller description

//6.save and exit

save patterns mapped.v -rep -verilog

report concurrent group -all

exit

mbist.do:
