Dear All :
I used to think that for prelayout gate level netlist , we can use nospecify and notimingcheck option to run simulation to verify wihtout sdf annotated . But I used these two option for both ncverilog and vcs , and result turn out to be different . Ncverilog failed while vcs passed .
I am now confused that whether should I use nospecify and notimingcheck again ? Or when should I use these option .
Thanks
