rom bist scripts

rom bist 的input 有rom_content file 。校验rom还坏，主要通过signature比较。signature跟rom content file 一一对应的。

rom bist scritps主要有三个：

1.rom_mbist_run: call mbistarchitect tool

2.rom_run.do:run rom bist flow

3.rom_mbist.do: 定义算法ROM1 输出 主要跟rom bist FSM 有关

rom_mbist_rum:

mbistarchitect ../netlist/rom_top.v  -top rom_top    -logfile rom_bist_log  -insertion -dofile  ../scripts/run.do -lverilog ../models/rom_instance.v -rep
