1. invoke problem
使用write_patterns保存pattern 做后续simulation时使用一些option来写出想要的格式， eg:
-verilog //pattern file 常用格式
-parallel -pattern_set scan //verifies each scan register can reliably capture, 省略shift，仿真capture
-serial -pattern_set chain // verifies all chains shift, 仿真shift，省略capture
-serial -pattern_set scan // verifies all chains shift and capture，仿真shift和capture，run的时间最长
2. reduce tips：
2.1 abort serial scan，run parallel scan + serial chain；
2.2 sample patterns in the early-time;
2.2 only run serial chain once for each fault type(stuck-at/transition)
