How to do postsimulation with hspice[help]

[sophiefans]

I am a student. I've never done postsimualtion before. Could someone tell me the detail? Reference with example will be better. And the layout has passed DRC&LVS.

Thanks in advance
sincerely

Hi,

do you mean a post-layout simulation? So do you already carried out a parasitic extraction and want to verify functionality after layout?
Please specify the tools you are using for layout, lvs and parasitic extraction. If you are using cadence dfII and assura for parasitic extraction, you get an so called extracted view after parasitic extraction. You can use this view to do the post-layout simulation.
In the attached document these steps are described (in german, but the images carry the important information).

kind regards,

you can extract the parasitic fater the layout is ready after LVS and DRC. if you use the starRC, you can choose extract the parasitic RC and seperate it with the original netlist, or combine them together.

If it only include the parasitic RC, you need to include the original netlist and the parasitic RC netlist. this is called back annotation. then you can kick off your hspice simulation.
