Hi, There's nothing in the command file that could explain the missing coupling cap, and it's unusual for an extractor to miss hundreds of fF. Are you getting any other Cc extracted to the net connected to nwell? Also, I assume none of these nets is a floating net. The default is to not remove any floating nets (atleast in EXT181) , but you could add filter_cap -exclude_floating_nets false to ensure. I'm afraid I can't guess much here. It will be quicker if you contacted Cadence customer support so someone can look at your layout and setup in a Webex session. Regards, Saloni![]()
