Hi all,
When laying out a Poly1-Poly2 cap primitive (analog checkbox in technology
preferences), Electric generates two nodes connecting to Poly1, and no
nodes connecting to Poly2. This way, the capacitor will not work properly
and fail NCC with poly-poly capacitors in schematics.
Here's a print of the layout with the properties window.

I have tried many different workarounds to use the primitive without
success. I believe the correct behavior would be either:
- Generate 2 metal contacts: one corresponding to Poly2 and one for
Poly1;
- Make the user able to connect an external Poly2 node to the
capacitor.
Another incorrect behavior is in the 3d view of this cell.

Again, since the contact is over Poly2 in the layout, it is expected to be
between the orange and blue layers, but the contact is actually between the
pink and blue layers, passing through Poly2.
I have tried to mess around with the technology file for a few hours, again
with no success.
I don't intend to use this cap, but a bug is a bug.
Best regards,
Raphael.
