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.
