Cadence Virtuoso LVS Error

calbear2009 over 15 years ago

Hi,

I am running LVS on my design, but

I have no clue what to make of the following LVS summary:

'the following layout ports are not texted'

'N_17, N_2...'

I've already added the correct metal-layer shape pins to my input/output ports.

so I am wondering what might be wrong. Thanks a lot.

Hi calbear2009

What is the LVS tool which you are using? Calibre? Assura? or ... ? : )

Best regards
Quek

It sounds like you haven't added the text labels defining the ports.

I am using a combination of Hercules/ACE process flow.
The LVS tool is Hercules.

hi,
I've already added the text label associated with each shape pin I've created (VDD, VSS, IN, etc..).
I used the XL Probe to check connectivity, and each pin seems to correspond with its associated pin in schematic (although it only highlights the schematic pins and not the wires connected to that pin). I'm not sure if that explains anything. Is there something extra I have to do for my ports?

Hercules is by Synopsys, you should ask on their forum.
