Cadence understand Poly resistor as a poly contact problem

Senan

Hello,

I am using Cadence Virtuoso tools version IC6.1.8-64b.500.6 with the Assura package.

During the layout of the poly resistor, I usually insert it as a PCELL by using "Connectivity" > "Generate"> "Selected from Source". The resistor is then inserted with all required layers.

During verifying my circuit with CAS, it shows me shorts in the locations between the resistor terminals, it means he understands the poly as contact shortening the two terminals of what is supposed to be the resistor.

How can inform Cadence to treat it as a resistor?

However, during the LVS check, the design pass correctly

While I have many resistors in my design, it is becoming annoying to differentiate between real shorts and those shorts in my design.

Thank you

Regards

    Not really sure if this is a PDK device, or how things are set up - customer support is the best approach here. 

    Perhaps you've got the extract depth set to greater than 0? If so, try setting it to 0 (which is the default) - that should help.

    Otherwise, please contact support.

    Thank you Anderw, I was using depth of 1 to follow my hierarchal design,

    I have made it 0 as you suggested and my issue solved,

    By the way, I am Europractice member and not sure if I am eligible to contact the customer support, also I didn't find the contact form to send my question

    Thank you once again for your help

    Glad that resolved it. Most of the time you don't need to set the extract depth to above 0.

    You can however go to Europractice for support. We work closely with Europractice, and if there's anything they can't handle, they are able to ask Cadence for support.
