ICC set operating condition 不起作用

liyong_ic

[size=+0]  最近使用ICC ，遇到下面一个问题。我在check_mw_design -power_net -verbose 时，
[size=+0]log 如下：

   我使用了如下命令set operating condition ，但是check_mw_design -power_nets -verbose -opcdtion_mismatches  后,还是有上面那些错误。不知道是为什么下面的命令不起作用！求解?

試試改成這樣
set_operating_conditions -analysis_type bc_wc \
             -max ss_1p62v_2p0v_125c -max_library gsmc18ls_ss_1p62v_2p0v_125c \
             -min ff_1p98v_3p6v_-40c -min_library gsmc18ls_ff_1p98v_3p6v_-40c

lvl，upf， mcmm，lp upf 这个是建立库最复杂的一块

建议你抛弃bc-wc，先走single corner，先check_mv_design ,  report_timing过了再说，
然后再进行mcmm的配置 ，加上min library，
mcmm的时候可能 要增加几个port state 和pst state，来满足min scenario下电压不一样的需求，

-analysis_mode bc_wc ,  set_min_library 是我最不推荐的方法，看的很糊涂，

-object_list的用法没错 ，  单独针对某些特殊cell，如lvl cells，

flash不用

請問這個問題你解決了嗎?

我現在是在synthesis階段,Design Compiler也給我同樣的error

用single corner lib也有这种问题么，

大佬这个问题解决了嘛，求解啊
