Sorry that it's taken a little while to get back to you on this. Honestly, I'm not sure why we didn't have any AC caps in the design kit so apologies there. As for the any ideas, please see the other thread on the community about AC caps. At the bottom of the thread, there is a VHDL-AMS fast settling cap that will remove the charge time on the capacitor but still give you the results that you would expect as far as removing the offset. Let me know if this helps you.
Thanks for the answer. I ended up modeling the series caps as low valued resistors. It doesn't give me a fully accurate result, but I think it is giving me good SI data.
That's reasonable to get the SI results, but as you noted, it's not completely accurate because of the offset. If you have to go back and do any more sims on that link, give that VHDL-AMS cap a try.
