Hi,
I am drawing the layout using a ctmm5 capacitor in xfab 180 process. The auto generated layout has metal 2 to 5 all connected by vias. I don't know what is supposed to be the other pin for the capacitor. When I run DRC it gives me these two errors. Thanks.

I don't see a reason to believe that all the layers are connected
by vias. Alternating layers -should- be. DRC says they are not.

I think you are missing the "stubs" to make that so. A
M3/V3/M4/V4/M5 stub-stack, where M4 is spaced from the
cap-plate anf M3, M5 connect those plates; A M2/V2/M3/V3/M4
stub-stack where M3 is spaced and M2, M4 conect.

Those "stubs" will be your connections to the rest of the circuit
(well, you could connect to anywhere on the plates).
