Cadence layout, intersection of metals (beginner question)

[Kamal__]

Hello all.
I am an absolute beginner in layouting. I am designing a layout (in Cadence) for a circuit which is not very complex, just connecting the gates together with the metal. However, I dont know what to do when two different metal wires overlap and hence they are shorted. I tried using different metal layers, but since the input pins of all the gates are met1 I cant connect them together.
I have attached a snip below. I know it is a very basic question but I would appreciate any help.

Best regards,
Kamal

Hi there,

you shorted them all right

Pin layer can be changed to any layer, really. Just select the object, hit "Q" and select your layer-purpose pair (LPP)... Say, "metal3 pin"
In many PDKs the pin object in layout is only used by the EDA software (Layout L/XL in this case) for hierarchy and routing.
The pin for LVS test is usually just a text label (pin name from schematic) in specific/special LPP.

Hope this helps...

"Vias" are your missing clue. You break the offending line,
move it up to Met2 ("q" = property edit), and connect the
segments with via1 at the start, and whatever's wanted
at the other end.

Hi,

Or you can hit "o" for "contacts" menu and in the pop-up window, you can select via between M1 and M2....
I did not add this to my original answer, because I thought this is not an issue, since you already have contact between poly and M1 in your layout....

Thank you all for your answers. Yes I didn't think of putting vias between met1 and met2 . Now it is alright.
