Hi, has anyone run into this before? The capacitors in my design are missing when I add the '`ext2spice extresist on`' option in the netlist extraction. There should be 112 caps as extracted in Class_D.spice, which is the netlist without any parasitic. But there are only three caps in Class_D_post.spice, which is the netlist extracted with the "extresist on". My command used for extraction is this:
extract all
ext2sim label on
ext2sim
extresist toleracne 10
extresist
ext2spice scale off
ext2spice cthresh 1f
ext2spice extresist on
ext2spice format ngspice
ext2spice
