Creating a custom resistor from single metal layer in Cadence for transmission line ports

Hey all,

I'd like to create a very simple, low value "resistor" (i.e. .01 ohms)
in Cadence, one that I could have a symbol for in schematics and a
layout that would be extracted properly in Calibre. Does anyone know of
a way to do this using just one layer of metal (with input/output
ports)? If I had such a cell, I could use it to solve several
connection problems (such as shorting an RF transmission line stub, or
putting ports on a transmission line structure). I'd like to just
insert this strip of metal in my transmission lines at the ports, and
still have the structure be evaluated properly for DRC checks (antenna
rules, etc.) and LVS.

Many thanks,

Jason May

Jason,

does your design kit not provide such 'metal resistros'.
In general they were drawn with a over lying dummy layer
for device recognition in LVS.

I did not understand the exact problem here.

It looks like it does have it, that should work. Thanks!

Yep, there's even a symbol r_dummy that I can put in the schematic.
Perfect!
